Love life.

So my mother has this opinion that I only want fwb’s when the truth is that the guy that she wants me to be with... i don’t love. I had dated him on and off since highschool. He is a great guy I just don’t love him. My moms feels that if I’m not with him that I am basically fucking up my life. She says that guys ruin my life and that I should just basically settle with this guy. I don’t feel I should do that. It would just be bad for him and worse for me. I don’t love him but how can I get my mom to see that he is just NOT right for me.
