Search Results: will he ask me out flirt

I have already met my soulmate who i can never be together with and we aren't in contact anymore. He helped me and i helped him and our roles in each other's lives are over. So i don't have to worry about "the one"
The biggest deal breaker in a relationship for me is cheating and i have always advised a break up if your SO cheats. Cheating is the same reason why i am scared to be in a relationship too. It seems that many people here and irl supports cheating too. I had a guy tell me he will pour sulphuric acid on to my face because i asked a girl to break up with her cheating boyfriend. I know a female user here who everyone compliments on how she's such a submissive good girlfriend while she's flirting and sexting her guy friend. Even some of my friends in committed relations talk about new crushes and flirting with hot losers.(They say it's for fun)
Whenever i express my hatred towards cheating, people ask "Did you get cheated on or something?". Obviously i did not. But i feel like what they're saying is i don't have the right to be upset about cheating.
Anyway i got a player guy who have always wanted to "date" me since i am not easy and i am 99.9% sure he will cheat. So if i date him and when he cheats, i may finally be able to get rid of my fear. Once i become immune, i believe that i won't be always thinking if my future SO (someone i love) is cheating and even if he is, I would be used to it.
You would feel like i am being a hypocrite rn so i will stop expressing my anger towards cheating and such questions from this moment onwards. And yes i am alright being a miserable girl who would probably be pitied on (Ik i need help🤷‍♀️).

So to start my boyfriend and I are in a long distance relationship. He has been a lot less affectionate the past couple weeks, and really stopped showing me that I matter to him altogether. He still says I love you but that’s only when I say it first and I don’t know if that’s just how he is and if i should lower my expectations. The other day he had oysters for dinner and sent me a screenshot of him googling what oysters do to men for sex (just a brief explanation from google) which i didn’t think much about at all and just thought he was flirting. But then I realized that he took that screenshot almost half an hour before sending it to me. This hasn’t been the first time he’s made me question if he’s seeing someone else but whenever i ask he gets really offensive and makes it seem like i’m the bad one while he continues to avoid and deny the question. I really need help on what I should do and any opinions will be really appreciated!!
