Search Results: insecure about cheating

So first off.. my previous relationship messed me up big time. My ex cheated on me.. this was 4 years ago. I never loved my ex but still.. it hurts.
So i still have some trust issues with guys
I have been with my current boyfriend for over a year
Ever since my ex cheated, i have been insecure about myself
So I've been insecure during my relationship with my current boyfriend
Recently its been worse
Sometimes i would accuse my boyfriend of cheating.. or doing something dodgy behind my back
Last night he messaged me something " this pic is for you babe😚😚😚"
But i didn't see the picture
So i thought he sent it to another girl and accidently messaged me
So i called him straight away and said "who did u send the pic too? Wheres the pic?"
And he said "i sent u already. I sent u the pic first and then messaged u"
And then i said "now i saw the picture... u sent it after u messaged. Did u send it to the wrong girl? Did u send the pic to another girl?"
And he goes "wtf? I only sent it to you. Maybe ur internet is slow thats why the pic didn't go through. The pic was only meant for u"
And then i said "are u sure?"
Then he said "look if you think im cheating on you, just dump me. Simple. I've told u million of times that im not cheating on u and that i wanna be with u only. If i wanted to cheat, i wouldve done it ages ago. Stop being insecure. Just dump me if u dont trust me and think im cheating"
doesn't that mean he doesn't care?
He doesn't care if we broke up?
Was i in the wrong or him?

Me and my boyfriend have been dating for over a year
We do have our ups and downs but he has never cheated on me
I would know if a guy is cheating coz my ex did so i would know the signs..
But anyway.. my boyfriend has been training at gym for 5 years and has been improving ever since. He used to be soo skinny but now he's quite built
He has been focusing on training at gym a lot lately
He goes to gym 5 or 6 nights a week
He tells me his plans about it for future
This is our conversation:
Him - when im more ripped, im going to go for photoshoots. I've always wanted to. And when I get those photos, I will upload them on instagram and will put my profile on public. Oh and im telling u in advance, im going to have shirtless photos too.
Me - why? To get attention from other girls?
Him - wtf? No.. im doing it for myself. And i want to motivate people. Im not doing it for women.
Me - it just shows you want other girls to pursue you
Him - well they might but im not going to do anything about it and i can't anyway. Its not like im going to go with them.. I have you already. I dont got time for 2 girls anyway. I have shit to do. Stop being insecure. Im doing this for myself, for me to see my progression overtime and for other people to see what I've become from years ago.
Am i right to be worried about this?
Do u think im right that he wants to do this so he gets attention from other girls? Or does he sound genuine about it?
Some girls are real thirsty AF so thats why im just thinking of stuff like other pretty girls will try to get with him etc
Or is this my insecurity?
My boyfriend is quite good looking so... I don't know
