Should I just leave?

LONG... so I’m writing this with tears in my eyes because I am honestly just lost at this point.. I’m very sorry if this gets confusing or doesn’t make much sense but I’m going to try my hardest. So I been with my boyfriend almost going on 3 years.. we have 2 kids together one girl ( almost 2) and a boy ( born the 3rd). (Now before I really get into it I would like to add that his mother died of a drug overdose when he was little so his aunt and uncle took him in. He was a trial and error kid. Wasn’t taught love or affection at all. No attention always had to be the man etc etc.. so I know it kinda plays a part in this but still...) okay before I had my son it was just me him and my daughter. EVERYTIME is was/ is off work he will spend HOURS playing videos games and in talking HOURS ladies like 18-19 hours AT A TIME. I got no help around the house, no help with our daughter etc.. we moved in this house February of last year from now until then and I’m not joking when I say this, he has probably changed her 5 times and the rest was me. He doesn’t feed her, hardly holds her, doesn’t play with her ( the game is more important apparently) I did/do it all. Now before everyone suggests “ talking to him” I tried many and many of times. Each time he says “ I’m sorry baby I really do love you and I didn’t realize I promise I’ll help you” and my dumb ass falls for it everytime he’ll help for maybe a day then go back to completely ignoring her and I both. He doesn’t kiss me, hug me hardly ever have sex( he says it’s because he was scared to hurt the baby) but he sure as heck can watch porn🙄 (been caught many times) I literally have to BEG for him to spend a little time with me and after hours and hours of begging he either gets irritated says “ god you are so damn persistent can you just leave me alone” so I just end up going upstairs with my daughter snuggling her or playing with her trying not to let her see me cry. Or sometimes when I’m lucky he’ll say “ fine for a few minutes” and it’s literally few minutes ill be extremely lucky if I get an hour of his time. Now he does work so I do not have to and that I am thankful for. He works 7 at night till 7 in the morning so he sleeps during the day which I honestly understand and don’t have a problem with BUT he’ll come home about 8am and play the damn game till about 11-12 then go to sleep and wake up 15 minutes before he has to leave the house to be ready!! That leaves no time to see his daughter, me, and now our son. There’s no reason why he can’t spend time with us from

8-11 when he comes home or go to bed when he gets home and wake up earlier before work like 3 and spend a little time with us. I wash, dry and fold his work clothes I set them out for him when he wakes up along with belt shoes work bag etc so he doesn’t have to rush around to find everything and yet this is still how I’m treated? He has his schedule for the whole year. One week he will work Monday Tuesday off Wednesday Thursday work Friday Saturday Sunday. Then the next week he’ll be off Monday Tuesday work Wednesday Thursday and off Friday Saturday Sunday. He works 12 hour shifts so I understand he’s tried but just these past 2 days he was off he didn’t help me with our son or daughter at all. He slept and then when he woke up it was straight to the game. Last night he stayed up ALL night playing so now he’s sleeping and he’s going to be sleeping until he has to be up for work at 5:45 so that’s absolutely no time spent with me our daughter or our son. At the hospital when our son was born he went home to “ sleep” because it was so uncomfortable there he couldn’t sleep with the nurses coming in every hour or so found out he came home and was on the game for a few hours.. while I was alone at the hospital 😔 he told me to text his grandma a kid from his phone because he was going to sleep yesterday and I happened to snoop a little and saw text messages from his friend and his friend was asking for my boyfriend to take him or go get wax from my boyfriends cousin then my boyfriend said something about the baby being born and his friend said “ oh never mind you gotta spend time with your family” and my boyfriend said “ nah it’s okay I can wait to see if he wakes up soon and get you something bud” so he was or maybe even did idk make me wait to come back to the hospital because he didn’t come back till 11 the next day so that he could get wax from his cousin to give to his buddy.. we had a dr appointment for our son Tuesday morning I got in the back because I honestly was worried about the baby but when I got back there was a random monster and I asked him “ babe why is there a monster back here you’re never back here” and he said “ I don’t have to tell you who’s in my car” and he honestly said it kinda playfully like he was just trying to annoy me so I just let it go but I haven’t been able to stop thinking about it sense.... I thought things would change when our son was born he promise me they would.. promised he’d get rid of the game system If he had to.. nothing’s changed. Speaking of changed my son was born on the 3rd he hasn’t changed his diaper. Hardly held him in the hospital and now hardly helps me at home and mayne has held him 3-4 times for 10-15 minutes sense we got home on the 5th. I really am in love with this man and the thought of not being with him brings tears to my eyes every time and I really don’t want my kids to be without a father but when does enough become enough? I’m at my breaking point. I want it to work out and be a happy family so badly but I just don’t know if we can ever get to that point.. so I’m asking would you leave? Would you try making it work? Like I said trying to talk to him doesn’t really work.. I’m just at a loss.. thank you 😔💕
