Search Results: me and me best friend like each other

Hey everyone so my boyfriend left me 2 weeks ago for personal problems. He was tired, sad, and felt bored. He swore I was not the issue and has made an effort to stay friends. the first week of being friends we hung out, held hands, kissed etc. It was like we were dating with no label and we both agreed it needed to stop. So we did. He didn't know what he wanted, he said he felt numb and depressed. A few nights ago he said leaving me made him feel even worse and that I was not the issue at all but that he knew he couldn't get into a relationship with me until he figured out his issue. He said he wanted to prioritize his mental health. I was super upset but also really understanding. I have gone minimal contact with him for about 2 days now and have done my best to give him space and distance to figure out his life. Today he invited me to dinner, said he had an extremely hard day and wanted a hug and to see me. I understand we broke up but we have love for each other and he has stayed loyal completely anyways. Do I go and risk getting my hopes up? Do I go and remind myself its just a friend and not expect anything. Or, do I say no and risk him being upset or thinking i've moved on.

So I met my best friend a little over a year and a half ago. We both work at the same place and hang out outside of work and go to the same college (we were basically roommates). I was originally “in love” with another guy whenever we started hanging out, and he helped show me that he was toxic for me. After that, I was able to get over that guy and focus on myself. Doing that, I realized that I actually had feelings for my best friend. I thought it was nothing at first, but throughout our friendship, those feelings have grown a lot stronger.
We both love Star Wars and Marvel. He makes sure I know that I am invited to different events that he is going to and tries to include me in everything. We go on late night drives (just the two of us) and listen to music or talk if either of us are upset or overwhelmed. People always know that he rides shotgun in my car because he designated himself as my co-pilot. I have had a few people ask me if we were dating because of how we act with each other.
The reason I haven’t told him yet is because he has a girlfriend. This hasn’t been a long-term girlfriend, but it’s been going well for them so far. He’s fallen for both of my best friends in the past and I’ve always been there to give him advice about any of the girls he was thinking about dating. Currently, his girlfriend and him are doing well (other than one night that they got in a fight and he ended up crying and talking to me about it).
I’ve had the overwhelming urge to tell him lately because my feelings are growing so strong and it hurts me a lot of the time. He’s also been teasing me a lot lately (jokingly) and is always cracking inside jokes with me which hasn’t helped. His girlfriend is so great and I love her. I’m just scared that I’m gonna go insane if I don’t tell him. I also don’t want to lose him as a friend because I don’t think I’ll be able to handle it. People keep telling me to let it run it’s course and I’ll get over it, but I haven’t.

What should I do?
