While i'm in hospital, he looks up fit girls

What do you mean looking up girls ?

Like just searching on facebook ? Thats perfectly fine

Stop being jealous and trying to control your boyfriend. Let him be a man and let him enjoy looking other girls.

If it's just friends, no big deal. I agree, though, if he knows you don't like it and still continues to do it, he either doesn't care and will tell you it's just what he does, or, he's actively looking elsewhere and wants you on the shelf.

Woman I'm currently, and, for the second time around, dating does something like this (funny, she's also in the hospital fairly often, and I don't look anyone up). We'll be out at a pub or something, and, she'll talk to seemingly every guy within our immediate range. If they start talking to her or us, she'll keep things going, sometimes 15-20 minutes. Even gone outside for a smoke with one (who did, at least, ask if it was ok with me first). One night, I asked/told her "Do you have to talk to every guy around? Wouldn't like it if I chatted up other women, would you?", and she said "You don't want me to be me".

I told her, yes I do, BUT...I feel disrespected when I take you out, we have a good time, yet, other guys are involved at some point. My best line to her was "I'm not paying a bill to serve you up to other guys". Has she stopped? Not entirely, but that's also due to my being more careful where I take her and where we sit. I pretty much avoid sitting us at a bar with other guys, or at least, other guys she's likely to talk to (middle aged, married guys seem to be off limits for her..no interest).

Sounds like your bf is similar..He'll tell you that you don't want him to be him when he's looking up other women. Put a stop to it, or tell him hit the road. Nobody deserves to be disrespected like that.

If he knows it bothers you and he continues to do it, especially while you're in the hospital, I think that's a red flag and you should probably move on.
