Online models

This is probably going to sound really immature or bad on my part but I’m just after advice/opinions..

Me and a guy have been talking for over a month now, we met last Monday and everything’s been great, I’m catching feelings, and I think he feels the same way.

But the reality of dating again has kinda hit me, all my insecurities and worries and stresses having to come back again. For example, last night I saw that he follows a few models who post lots of body photos, and it made me feel really insecure about myself and that I have a lot to change and live up to before I’ll be good enough.

The reason I feel like this, is because my ex really fucked me over and broke me down. He followed the same types of thing, spent 2 years telling me I was perfect and my body was and that he didn’t even like those sort of bodies/girls.. when he was actually cheating on me for the whole 2 years with those types of girls.

So I guess now I’m scared, how do I become good enough, how do I get the confidence that just because this guy follows models and stuff that I’ll be worth it? This guy is a lot better looking than me, fitter body, he can do so much better.

Does anyone else feel this way? How do you overcome it? What do I do?
