not child related but relationship advice is soooo needed....

I'm the mother of a great Autistic 2 year old son..... his father left when he was 8 months old and has had no contact since.

anywho after my son's father I stayed single. no one even caught my eye. and then I met Ryan. who has been so great to me and my son. however I've knoticed alot of things about him. such as he Constantly Needs to be talking to me. if I don't answer he'll keep texting and say things like "ok text me when your free" "have a good day" "guess you don't want to talk" or big giant paragraphs about his love for me. last weekend we had a super rough weekend of fighting. I was coming home to have a couple of drinks with my best girlfriend and that wasn't okay I'm his eyes. I lost his shit and screamed at me. I didn't wanna fight so i say on the couch while he was in his room. he came out and placed an sort pill bottle for me to find. the pills were next to him. he claims he was never going to take them it was just to egg me on....

on top of this. before we got into a relationship he asked me if I've ever cheated and I answered honestly how I cheated on my son's father but only in retaliation to his cheating on me... ever since he has questioned if I'm cheating. at first it was he's question of I had feelings for a friend. then it was he found a really old auto backed up photo of my son's father. that wasn't okay. (I deleted it the second I was able to figure out how) next he texts me with a "I feel ugly today" I said "I don't think so you're the most handsomest" he says "really cause that's not what I saw" I asked him what that meant and he tells me he went and saw my friend Joe (whom I rarely ever talk to always were just friends) on Facebook and decided he was better looking. after this I was accused of flirting with my friend. i gave him my facebook info to scope it out. says he would never go on it cause he trusts me. whatever whatever. continued to say he didnt touch it.... just to find out he did go in and scope it out.... says he trusts me.... but it's clear he doesn't? is he crazy or insecure? I'm at a loss of what to do
