gotta get this out or I'm gonna blow up... my so has never done anything to make me think he'd cheat on me, he doesn't talk to girls and every time one messages him right away he shows me.. that being said I have horrible trust issues with people in general. I don't feel good enough at all for anyone not just him and even though he makes me feel beautiful all the time I still know I'm not.. he's dated so many girls and they are all so beautiful like models. he's friends with all of them on Facebook and when he goes through his timeline he stops and looks at them and has liked a few he says it's not in a flirty way and it's not like dirty girls with their boobs out just normal pictures. I now I'm being crazy and since I've been pregnant I feel so fat and gross.. today I don't know what's going on but everything is just going to shit. I know I should trust him cause he hasn't and he knows I'd leave without questions but idk.. maybe i need to tell him how I feel I know he'd understand. being a girl today I'm sorry
