This might sound really immature but I'm seriously debating it. Basically my boyfriend cheated on me and although i have given him a second chance im not fully convinced he doesnt want to do it again.

Meanwhile I dont know if I could find better? Ive been debating getting an app like tinder or bumble just to look around and see what other guys might be out there. Problem is I fully love my boyfriend so much so that I barely find any other man remotely attractive. So i dont think i would find anyone. I dont want to kiss or do anything with anyone else. But the fact i feel like he does it making me think i should too?

We live together and im too afraid of losing him, my best friend who has been by my side over 4 years, to just break up.

Hes mentioned an open relationship many times and maybe we should try it? I know it will break my heart but maybe i will find someone or he will realise he doesnt want me with anyone else? He just wants to sleep around but have me all to himself.

Like i believe he probably does love me i just wish he was less obsessed with sex and girls that he could be happy with just me or threesomes with me included.
