We do have sex, and I enjoy it a lot. He helps me out with practical things a lot, and since school switched to online classes and exams, he suggested I do all the exams and some of the studying at his place, moves furniture into a spare room which he lets me use as a study, just to help me out. He lets me stay even when he's at work. He's a good cook and says he really enjoys cooking for me and having me over. I think I love him, but I'm very afraid he may only see me as casual. We've been together for 4 months now. Opinions please?
