Search Results: changing behavior

So there’s this guy I met a long time ago on a dating site my friend made for me. He lives in the UK and I live in the USA. We dated for a couple of months before he ended it due to his mental health. We have been talking on and off ever since then, and he claimed he’s changed for the better like he’s gotten the help he needed and understands that his behavior before towards me was bad.

so last week, he mentioned that he would like to restart a relationship with me because he realized that in every relationship he’s been in all he could think about was me (I don't know how true that is). I was obviously flattered at the time and entertained the idea some just because I thought it was genuine. However, the next day he ended it saying that he was getting ahead of himself and basically canceled everything he said before stating that his mental health is not doing as good as he thought right now. He said he’d be off of social media as well for a couple of weeks to get his mental state together but now I see him posting stories online only after a week of last talking to him so he lied about that. I’m not sure how to feel about it besides betrayed for the lack of better words or disposable. What do you think?

I used a cosmetic product which most likely resulted in severe irreversible adverse effects. 8-months ago I reached out to a top doctor by email. Over the 8-months he enthusiastically and quickly responded to all my emails providing his medical opinions and even zoomed with me. I gave him a false name to conceal my identity (HIPPA) given the initial email nature of our communication. I recently flew across the country to be examined by him free of charge. When I got to his office, I informed him of my real name and explained that I used a false name in our communication to protect my identity, which he seemed to be understanding of. The doctor told me to email him pictures upon my arrival back to California to complete his assessment/opinion of the potential diagnosis or lack there of. Upon my arrival back home, I emailed him the pictures and thanked him. I also shipped him a small gift. After 3-days, I received an email response from him saying that he very briefly looked at my pictures. He stated that although the pictures I sent him are blurry he will do his best to give me his opinion on Monday. I didn’t hear from him for 7 days. After 7-days, I sent him a follow-up thank you email. I never heard from him again. Its now been a month since i've heard from him. There was a big change in his behavior after our medical visit together. He went from merrily answering me within minutes; to sort of ghosting me despite knowing how terrified I was awaiting his opinion/recommendations. Which do you think is the MOST likely reason (s) he has not responded to my email?
