Idk what the f$&@ I’m doing anymore

So I met this guy through a friend I’ve known for 3 years, we hit it off right way he does come with a heavy past with charges of attempted murder when he was 19 now at 28 he’s spent YEARS in prison and currently on parole now I’m a single mother of 4 I have my shit together all the way no questions, but dealing with this situation was like 💭 do I over look his past or walk away?... I stayed ! 🙄 we hung out, we shared stories of our past, made plans for the future moving forward. Since it was so new I didn’t want sex rt away and he wasn’t to meet my kids till we had a few month in. One weekend we went out and we ended up having sex 🤦🏻‍♀️ so he agreed we’d do this long term no matter what he wanted it as bad as me ... so I thought 😏Well today me being tired raising kids and finding out I now have what the doctors think is a “bladder infection” being up all night from it, I fell asleep and we had plans he’d come over after the kids go to bed. Well I woke up to no calls, no text so I call him like “ hey! I fell asleep are you still coming over?”. NO! He goes off the deep end hangs up on me won’t answer so... I text him like “what’s going we’re suppose to communicate I’m sorry I was tired” NO RESPONSE, so .....I call him NO ANSWER then he texts me “you pissed me off see you tmw “. My response was UMMMMM WTF? “ why aren’t me communicating? Why are you so mad ? Etc ...So he chose to ignore me more then he texts me “I’m drunk 😒 you pissed me off now don’t make this worse I see you tmw” Now I’m laying here thinking 🤔 This is a “man” who has a past rt, drinking on parole, and throwing a tantrum because I fell asleep with what I know now has poor communication skills do I really want this type of bs in my life ..no ! but I’m like he works full time, loving when he’s not drunk from what I noticed and seems legit about having a relationship and getting on the rt track Soooooo idk if I walk with all the big red flags or is this just a fight we can get though ? Let me hear it girls 😔😩
