I can relate to your situation, the only girl I’ve ever loved broke up with me with a major reason being that I decided I wouldn’t spend the night in the same bed as her during our relationship. It seems like you already know what the Church teaches on sexual purity, so from there it’s really a matter of do you want to follow the Church or do you want to make your dating life easier? I hope saying it like that doesn’t diminish how difficult navigating this stuff is, but that question is the conclusion I’ve gotten to when it comes to modern dating. Deciding to follow the Church’s teaching on this has made dating next to impossible for me which why I haven’t been in another actual relationship for a few years at this point. However, if obeying the Church’s teaching on this subject results in me never finding a wife, then I can know that was what God willed for my time here and following Him is more important than anything this world has to offer. Also, in my experience I’ve noticed that anytime I find me practicing my faith comes in conflict with the world or makes my life more difficult, it usually means that I’m doing something right and that realization has given me a lot of peace.
