Background: My mom left my dad when I was 8 for a woman 20 years younger than her. My best friend's dad did essentially the same thing a few months later. My other friend's dad left her mom when he stopped believing he would go to hell if he got divorced and, as my friend put it, "would rather smoke weed on the beach and screw 20 year olds than take take care of his family." So I've been afraid of this kind of thing happening since I was a kid and it doesn't feel like there's anything I can do to prevent it since my friends' moms were in great shape, kept their homes immaculate, and one of them was really beautiful. After they divorced, I found a picture of my dad in a heart-shaped frame in my mom's dresser and I realized that she was still in love with him. I told myself that I would never be like that, and that I would break up with any boyfriend I had at 40 and just be alone the rest of my life so that I wouldn't have to go through the pain of him trading me in for a younger woman.

I fell hard for a guy and was with him for a year when I learned from a mutual friend that he believes in redpill ideas like the wall. I read about redpill and some of the stuff didn't ring true to me (this guy works part-time and lives with his parents and idgaf and chose him over more materially successful men), but the part about the wall kind of makes sense to me given what I saw my mom/my friends' moms go through as a kid. The scariest part was that according to this ideology women become less attractive in their 30s whereas I had thought they only started becoming less attractive in their 40s, so it suddenly seemed like I didn't have plenty of time anymore.

I asked him if he thinks he will become less attracted to me as I get older and he said that he will but that he will not break up with me, will still love me, and that how I look is just one small part of my value. He said that he thinks women are generally more beautiful in their 20s than their 30s but I take good care of myself so I'll stay pretty for longer. I'm terrified he will trade me in for someone younger when he inherits his parents' assets, at which point I'll probably be around 40 or so...standard time for trading up. I decided I will leave him when I turn 30 next year so I don't have to go through him becoming less attracted to me, but whenever I think about leaving him I become completely miserable. I don't think I could ever be happy with anyone else. I get hit on a lot so on some level I think I must be attractive but since I heard about the wall I hate my body and don't want to leave the house. Sex has stopped being fun for me and I don't like being naked around my partner because I feel ashamed of my body now.

Do you think this would get better if I stopped dating someone redpill? Is there any way to make peace with my body? And if women really stop being attractive in their thirties then why do so many successful men including some redpill/MRA leaders choose to marry women in their 30s and 40s and stay with them as they get older? My landlady is in her 60s and her boyfriend who she started dating in her mid-40s is a tall software engineer who takes her on trips to Europe every summer, how is that even possible if redpill is correct? We all get old so if the wall is totally legitimate, then why would any guy get married in the first place if they know they're just going to stop finding their wife attractive in a few years?

Tl;dr Should I break up with my boyfriend when I turn 30 because he believes in the wall? Not interested in being with someone who isn't physically attracted to me. Why do successful men get married if they know they're just going to stop being attracted to their wives in a few years?
