My ex that Im still friends with is still in love with me…

Talking abt this here bc I have no where else to put it lol

So me and my friend (we’ll call him guitar boy) used to date like 3 years ago when we were in like 7th grade(?). Our relationship lasted abt 7 months and I broke up with him bc I js kinda fell out of love (Im notoriously bad at relationships) since then we both have dated a few other people but he’s confessed to me again once or twice. Once we both became sophomores I thought he’d finally gotten over it and we were good. Until in September I started taking an interest in him again… 

I (like an idiot) hinted at me liking him again and ive never regretted smth more. Not even 2 weeks later I realized I was js rlly stoked to be his friend and was NOT romantically interested in him. I think from that point forward he always said he had 2 crushes. One he wld tell our friend group abt no problem and one he kept super secret(me). He wld talk abt how he’s “liked this person for so long” and how he “wished they wld js look at him the same.” It was excruciating bc everyone knew who he was talking abt. He calmed down for a bit but wld now avoid questions abt his crush/love life and get weird when I talked abt mine. 

Fast forward to late December. I js got done with what I consider the worst breakup of my life and am js at a rlly low point.

A few weeks later Guitar boy starts talking to me more. 

I start talking to him more.

We start flirting.

The attention makes me feel better.

Im cooked.

I very quickly realized that he was js genuinely in love with me still and I felt rlly bad bc I was now js leading him on. I stopped for a little bit but regrettably it did happen a few more times. I stopped for good bc I do care abt him and I knew that it was rlly shitty thing to do in the first place. I told him that we would not work out and was not the best person to be in a relationship with.(commitment issues, lack of self control, all that jazz) however, that did nothing and he is still in love with me.

Now hes been posting instagram notes with songs related to our past relationship and stuff like “cried over a boy last night” and “Im starving for his attention” Im kinda hoping that he’ll js.. find someone else? Idk all I know is I don’t want him T^T
