Sharing Our Innermost Thoughts

There’s this guy at college, I’ve turned down his proposal more than 5 times and he’s still trying and I’m not liking it. He’s the one who came between me and the man I loved and created differences between both of us and now that we’ve broken up he’s trying again and trying to guilt trip me like Ive been waiting for you since so long, my heartbeat falls to 40 because of the condition he’s in. ( because I’m not accepting him) recently he’s trying to be overly involved in my life, by asking about my family members individually that how are they doing, I get it it’s kind of him but when I don’t ask about his family I don’t initiate conversations with him I avoid him as much as I can turn down his calls and everything all of this is just suffocating me. Please I need advice. I’m probably just thinking too much about it
