having cake and eating it too ?

would you ever date someone just because your family loved them and wouldnt accept anyone else and it "made things easier" ? would you be able to date someone you weren't sexually attracted to, barely had sex with and didn't even really enjoy the sex you had with them? my ex lover who I believe is my soul mate is doing this and even bought a house with her because he was told by his parents he had to move out. these are the things he tells me and this girl is basically a lunatic...I mean she got mad at him when he brought a puppy home! and he still wants to have sex with me! he tells me we had the best sex and that we make love and he only cums with me, all of this is so confusing to me, I could never be in a relationship with someone I didn't enjoy having sex with and wouldn't date them just to comply with my parents. I love him so much and I know he loves me but I feel like he's just trying to make everyone around him happy and is forgetting about himself
