7 months preggo and been cheated on :(

Long rant ! Well what can I say I'm 7 months pregnant, very hormonal and just before Xmas my live in boyfriend / baby daddy lied to me said he was going go to friends house play video games he been into drugs and was trying get away from it, but went out all night left him alone was idiot sending him sweet texts before I went to bed how I loves him and glad we working out . So 3am I got up to pee , went look on Snapchat his location was no where near the friend's house he was spose to be playing video games with he was out with his druggie friends drinking and doing drugs , Grace me with his presents at 3:45 am said he wasn't drinking or doing drugs even tho he was clearly drunk and on drugs anyways he passed out and I know his passcode to his phone so my gut instinct told me something up boy was I in for a shocker , he was texting and inboxing girls using our bad relationship try get with them and using buying baby stuff as he haven't yet to not give his druggie friends money he owes , talking bad about me and this one takes the cake are you ready girls if you haven't stayed for my long rant that night he cheated on me was with a guy got blow job from a guy lol 😂 I feel horrible still . But it is funny I'll laugh at this later down road . Says he not bi or gay was just drugs but I'm bot stupid the guy suck his cock is bi so they say bi or gay guys can suck cock better . May I added been living together he haven't helped out with a bill or groceries either. And we had sex daily so he was getting it at home .Just looking for support thanks in advance.
