I met a friend online fairly recently and we talked everyday (including hours long phone calls and video calls) for about 2.5 months. We really bonded and I was so certain he would never ghost me (he even said he will never leave me permanently without saying goodbye, which he still hasn't). However, he has technically ghosted 3x in the last month. We went from talking daily to 1x a week for 2 weeks, and now it's been almost another 2 weeks and nothing. I miss him very much, and every time he comes back he tells me how much he is struggling with his mental health and overwhelmed, but still says he cares and he misses me. He has bipolar, ADHD, PTSD, and a few undiagnosed things (he's untreated for all of it). Normally I would just try to move on but I really don't know if I can completely. He is very special to me and one of my closest friends ever. I also developed feelings for him over time (which were mutual). He has always been honest and open as well as super supportive. I just don't know how long to "wait" for him to come back. I tried a few times to reach out but no response this past week. I'm so hurt that I cry every few days. My other friend says I should just forget him, but I can't seem to stop thinking about him and to be honest I don't want to be without him.
