TL;DR How do you get a guy to commit to you if you have to have sex outside of marriage?

Now, this isn’t a problem for me anymore since I converted to Islam and am going to get married that way, but if I was single and non-Muslim, let’s say I was 5’4” and in the 200s, no cooking skills, not wife material at all whatsoever, the kind of girl men bring home but is so ugly they won’t show to friends, doesn’t know makeup, etc

How would I get a man to commit to me? They all want sex and now since it’s the 2020’s you have to have sex on the third date. Then they pump and dump you and blame you for a high body count… oh well.

Not that I’m really wife material but I don’t see that changing anytime soon. At least I can still get married through my imam.
