crush at uni

ive got a crush on a dude from uni but he has a girlfriend and i have a boyfriend. the thing is, i respect both of our relationships but honestly i think it's possible to be happier.

i suspect he has a thing for me too but is trying to keep it to one person at a time because whenever i come into lectures he keeps following me with his eyes and he looks at me sometimes etc. idk i might just be overthinking it but my hunch is usually right. how do i start talking to him to be his friend without seeming like a weirdo

Honestly, you know, if he has a girlfriend and you are currently in a relationship you need to let this go. He may look at you, he may find you attractive, you may think he's good-looking but all this is is a crush. You don't actually know him. Do you really want to risk your relationship on a hunch. You don't know that this guy is a fit for you because you don't know him.
If you want to get to know him better then come up with a reason to ask him a question - perhaps about something happening in the course you take together. Other than that I can't really think of a casual reason you'd go strike up a conversation with him.
But, until you hear he no longer has a girlfriend and you've moved on from your own then I suggest you just look at him from afar and keep your feelings to yourself. Sorry - my opinion.

Gotta take your leap of faith

don’t try to mess with his relationship just because you have an inkling. break up with the person you’re dating for both of your sakes. if this guy approaches you, fair enough, but its gross to become friends with him with the intention of possibly infiltrating his relationship which he may be perfectly happy in. remember that there is still another person involved here
