Using a throwaway because I post in local subs.

I'm 22M. I live with my grandpa. I moved in with him not too long ago.

My neighbor is in his early 40s I think. He is married. No kids. I personally have no interest in getting to know my neighbors but he greeted me during my move. Our initial interaction was normal, he seemed talkative, joked a lot, was nice.

Over the past months he's been chatting me up occasionally.

I have a gym set up in the garage and sometimes I leave the door open to work out. He started to come over. He'd talk to me about his body concerns. The first few times I didn't think much of it, but then I realized he's just fishing for compliments or wanting me to build him up. When he doesn't get the response he wants from me, he will start complimenting me instead. I'm assuming his intention is that I will return the favor. I don't.

He asked if he could workout with my equipment and I said no (politely). I just want to workout in peace. I like my space. That's one of the reasons I don't go to a public gym.

Unfortunately last month my grandpa gave him my phone number. My grandpa recently had a fall and it has made him a bit paranoid of his own mortality, so in his defense he was just trying to organize his own 'in case of emergency' plan which he is kinda anal about.

But I received the following text from the neighbor the same day: A shirtless photo of himself and a follow-up text in which he said he is 'getting fat' (he's not). I was at work and didn't reply but he saw that I read it and eventually sent me another text complaining about his high libido. (???)

I eventually replied with: Mr. [his name] We're not close enough for you to be talking to me like this.

His reply: How do I get close to you? 😚

Me: You don't. Join a gym, or maybe get a trainer. Good luck. I know [Grandpa's name] gave you my contact information, but it wasn't for this. Since we're neighbors, please only text me if it's an emergency.

He stopped texting me for a few days, then one day he called me stating it was an emergency. He asked me to come over because he cut himself badly and his wife has a phobia of blood. I regret the obligation I felt in that moment to help someone in need.

I went over there. He wasn't even injured. He was in a robe, seemed drunk, started laughing while telling me 'you really are a man of your word'. He then tried to hand me a drink as an apology while asking me to come in and hang out with him.

I told him to delete my number. He stopped contacting me via text, except one night around 2 a.m. where he just repeatedly texted me my name and then apologized because he was drunk. He then sent me a picture of his drink glass (as proof I guess?). When I didn't reply, he asked me what cologne I use. I didn't reply.

Last night, he called me again, stating another emergency. I hung up without hearing him out. Later I saw an ambulance arrive and about a few hours after that, he came to our door, repeatedly ringing the doorbell. I answered and he went off on me about hanging up on him, how we live in a rural area and it's important to stick close to one another and that he would never do that if I was in need (or my grandpa). He explained his wife had a seizure.

During this conversation, my grandpa found out I had ignored his request for help and is angry with me. He thinks I have sabotaged his relationship with the neighbor and he's spiralling a little bit about how he might not have any help in the future.

Did I really fuck up?

How do I fix it. I don't care about my neighbor, it's my gramps....
