I did. I was this man.
I am married and I started to date with other girl for a year and a half. We got along well, both of us have similar interests and we had an enjoyable time hanging out.
She was deeply in love with me and I told her that I loved her, even though I didn’t, because I didn’t want her to feel bad. I just like to have someone to hang out with me sometimes, so I think I would simply lie to make her feel better. I liked her, I enjoyed spending time with her, but I never loved her.
Why did I stay? Mainly because of fear of hurting her, and the other reason is if I broke up with her, my chances of finding someone else were low. I enjoyed spending time with her, I didn’t want those things to end. I realized that I made it worse in the end, I should have broken off with her earlier because I hurt her more in the end. Hopefully this explains why some people might stay in a relationship, even if they don’t love their partner.
