This is normal and will pass. The more you think about it the worse it gets - focus on her for a while and not on trying to get off yourself. Before you know it you're back up and running.

And please disregard all the dumbasses on here talking about how condoms are the problem. Be safe.

I'd try to meet up with her anyway. Seems like she'll have some interesting things to tell you about him if he's so desperate to keep you away from her.

Maybe you're tired, I get that, but keep on blocking him. Do not type a single word to him, do not answer his phone calls and when you accidentally do because you didn't know it was him, immediately hang up and block. Keep blocking and not responding.

Put your social media on private so people have to ask access first.
