My boyfriend acts 2 different ways when we are with each other and when we aren’t

I’ve noticed my bf acts one way when he’s with me and and another when we aren’t with each other . So I’ve noticed when we are with each other he wants us to lay up a lot and if we don’t he’ll feel like I’m acting weird and don’t wanna be around him (argument has started because of this) hell constantly text me or call me WHILE AT WORK . Knowing I’m at work and can’t answer fr but he’ll still do it . He’ll FaceTime me on break and talk and FaceTime me while I’m walking home . He’ll wanna come to the store with me all the time and if he end up not going I’ve notice him looking around our apartment complex looking for me . (He really thinks I’m cheating on him) but then I’ve notice when he’s not with me like at his moms house or something he don’t call , he’ll call every few hours to check on me then find a reason to hang up after like 5-10 min on the phone . Don’t text me as much . . I’ve noticed around 2 years ago we NEVER spend time together unless it was time for us to have sex , he’ll be up all night until the morning on Group FaceTime with his friends and in the morning I’ll go to work and he’ll be sleep and the cycle repeats every night , but then when he stop talking to them friends then he wants to spend more time with me ??! And when I sat down and thought about it I’ve been going thru this since we was kids . When we was 16-18 he will be out with his friends while I’m at my house with our daughter (or work or school) and all my texts will be ignored , he wouldn’t answer the phone even if I called back to back . But then when he goes to placement or jail he wants me to write him all these letter . He’s nice and not disrespectful, he found a way to call me for an extra day while he was in placement , made it happen for me to be put on his visiting list (cause he was a minor) and same when he went to actual jail and prison , he’s nice . When I was in my feelings snapping out on him he never yelled back he’d listen and be nice made sure he called and text and wrote letters but again now he’s home and when I come to him with a problem CALMLY he gets mad , disrespectful and etc . And lastly . I’ve noticed that ever since he went to a friends house yesterday night he didn’t FaceTime he . And when he did end up calling it was regular phone not FaceTime . It was midnight . He called me asking if I was still watching my show I said no and he said ok I’m going to let you go to sleeep cause I know you got work tomorrow . And literally didn’t call me . It’s the next morning and I still didn’t get a call or text . That’s weird because again he thinks I’m cheating on him so if I’m not with him he’ll call whatever time no matter what if I’m sleeping or not to FaceTime to see what I’m doing . If he’s at home he would wake me up out my sleep FOR ANY AND EVERYTHING . He don’t care about if I wanna take a nap or need to sleep for work he will still wake me up . He will wake me up just to ask how to change his Lock Screen picture . But now all of a sudden you go to a friends house and don’t call at all and it’s the next morning . Lmaooo
