Anybody else’s SO do this?

Idk why but my husband is always trying to look over my shoulder or come in for a kiss when I’m on my phone but I notice that he’s trying to look at what I’m doing on my phone which makes me feel like he doesn’t trust me for some reason. I do mention it and he says he isn’t trying to look at what I’m doing but he obviously is because ya know my 👀 do work. Mind you he’s the one that I shouldn’t trust but I decided to trust him anyway 🚩🚩 Back story. We were living with his mom and I was pregnant with our first child and it was Christmas eve. RIP baby angel. But anyway I got sent a picture from his ex of him sitting down laughing smoking a joint with all of his ex’s. Something didn’t sit right with me so I gave him a call and this mf lied to me saying he wasn’t there.. we got into a huge argument but I forgave him anyway and my dumb ass got pregnant again and we now have a 2 year old son and we live together 🚩🚩🚩🚩🚩🚩 part 2 of why I shouldn’t trust him: we broke up a decent amount of times in the past but decided we were gonna try and make it work for the sake of our son (I grew up without a father so I didn’t want my son to deal with the same thing) during the time we were broken up this mf instantly went onto dating apps like Facebook Dating, Tinder, Meet Me etc and I had no idea that he even was on those websites and he even went as far to change his Facebook password. We got back together a week later and he gave me his FB password so I logged in and saw that he was trying to talk to 5 other women the day we broke up so my heart ached over that for a while and still kinda does. Now atm I’m trying to study for a drivers test and he keeps telling me that it’s not that hard but I have wicked bad ADHD and dyslexia so it’s hard for me to concentrate on reading and he went ahead and told me that I probably shouldn’t get my license if I can’t read and it lead to a fight the first few times I tried asking him for help I mean a f**** screaming match for absolutely bo reason other than the fact that I needed help. When I tell him we should of stayed broken up the first time we split he went ahead and said “if it wasn’t for me you would still be in a huge hole” it’s almost like he doesn’t think I can live on my own. Because of this I am starting to find other people attractive and feel like I should leave him because the way we are acting towards each other is getting ridiculous. Idk what to do anymore and I also forgot to mention that we also work together and at this current moment he’s my only form of transportation to get to work so I can support my son.
