Feeling insecure about boyfriend joining gym?

Anonymous
I know I'm probably stupid for feeling this way but I can't help it.I think a lot of it has to do with how I see myself,I feel like he could do better. I'm unwell and I don't have much confidence, so obviously there is going to be really attractive,fit and healthy women at the gym. He has said to me he has never cheated and could never cheat on anyone. Yet he has gone behind my back and talked to an old flame, asking how she was and telling her she can come out if she wants(this was when he went and visited his country) and she has a boyfriend,he had messaged her just letting her know why he stopped talking to her and how she was.She had replied but after he messaged her saying she can come out if she wants, she hadn't replied. There wasn't any evidence of flirting either. He doesn't know I know this.Anyway that has made me so much more insecure now I'm worried about him going to the gym I don't want to tell him though he'll probably get annoyed.I can't help but compare myself to these women, how can I possibly measure up?What if he has women going up to him?And then knowing he's got some unwell loser of a girlfriend at home who doesn't work.Also he says he doesn't but when I'm with him in public, he tends to glance over at other women walking past. It makes me feel like sh*t even more.I don't know what to think :(. Am I silly for feeling this way if he is going to join a gym?
