Having a crush on anyone is pointless unless you’re actually going to actually have a genuine intimate relationship with the person. If you have a crush on someone while you’re in a relationship, well don’t bother pursuing that person you have the crush on, because you’ll only end up losing a way more meaningful mutual relationship with the man you’re already with. Having a crush isn’t worth losing your more genuine relationship for. If it turns out that you and your crush end up in an actual intimate relationship together, well, that’s nice, but you’re lucky if you can even get your crush to like you back in the same way that you like them. Some crushes aren’t worth the bother. Only pursue your crush if you’re single. Just be sure first.
