Looking for advice for myself (22F) and my boyfriend (44M).

I could really use some help! I'm not seeking opinions on the age gap—I understand that aspect already. We've been dating for quite a while, and I'm feeling conflicted about whether to continue the relationship or end it. He treats me very well, but I sometimes wonder if that's out of fear of losing me. He often shares how lucky he feels, gives me compliments, discusses our future together, and occasionally covers expenses (though I assure you, I'm not with him for his money). Lately, I’ve started to question if I'm really ready for a relationship or if I’m just bored with our current dynamic. It feels more like a friendship than a romance to me. I've had these thoughts before, and when I’ve shared them with him, it always ends the same way—I end up reminiscing about our good times and decide to stay. But I don’t want to remain together solely because of our history; I need to think about our future and whether it has potential. My mom isn’t very supportive of our relationship (which I understand), and he hasn't met anyone else in my family. I'm apprehensive about how they would react to the age difference. Meanwhile, I've met his family and friends. Given the time that's passed, I feel like if I’m serious about this relationship, he should have met my family by now. I worry about continuing in a relationship that my family won't support. On the flip side, I fear losing someone who treats me so well because I doubt I'll find that again. That brings me back to my earlier concern: is he nice to me out of genuine affection or fear of being alone again? He often mentions that I'm his last chance at love and happiness. This leaves me feeling lost. I dislike confrontation, yet I don’t want to prolong this uncertainty. Should I share my feelings with him again, risking being drawn back in? Or should I directly say that it feels more like a friendship and that I need some space? I appreciate any advice you might have! Sorry for the repetition; I'm just jotting down my thoughts as they come.
