Confused/unsure

Well ladies I'm in a hard spot in life I'll start from when the first relationship went bad to the new one and how I've come to this spot in life now.

Well fast forward to April me and my ex but father to my child we together going on four years since we were in high school things started to get really bad we broke up all the time and had fights even saw other people but always worked things out well in May we hit it hard we spilt up for a month start fooling around in June and that's when our omg oh no where I got pregnant after a year before trying I gave up hope and what not and we were still not together we were trying to talk things through well after finding out we were pregnant things shocking got worst so we just quit talking and everything for about a year I've seen him in the mean time for our daughter but never really spoke well being single for five months while pregnant my best friend from school came into our life's and was there for me my whole pregnancy and we started dating and have been together now a year but all he does now is play his game and work he don't help with my daughter and don't even like to go places with us he has little to no interest in our little family and it hurts my heart we fuss a lot to and thinks he can spend our money on games and giving it to his mom who is very capable of working but is to lazy so that bothers me bc if I get my child something it's a problem to him plus he'll eat everything in the house and not even think about me or her I'm just sick of it !!!

So fast forward to now my child's father my ex of four years is literally trying to get us back he's went and moved to a new state just for a job that pays good and has been talking to me everyday since he left and apologize to me on how he went about things for the whole year he's been out doing whatever and it has me lost bc I miss him and love him but can't seem to want to trust him bc he's said this once before just about five months ago and just quit talking to me bc of another female and I'm still with my boyfriend but he literally has no interest in wanting to do anything with me and my child he only cares about his game and sex and I'm not giving him any bc of this whole thing like I have no idea what to do how to do it I wanna believe my ex bc he seems legit about it but I'm unsure!!...... anyone have any advice for me.. 😭😭
