I'm in a relationship, have been for almost 2 years and its going well. the thing is, I'm sort of crushing on my partner's best friend. I have their insta/disc and I've chatted when them a few times. They're also in a relationship too but I don't know what to do considering its been a few months since ive felt like this. Should I wait until it dies down or should I act on it? should I just break up with my current partner? I don't know.. I don't know if anyone else experiences this too, and I feel kinda shitty for having these feelings
