I was on a app for learning language and began a friendship with someone from abroad. We got on so well and messaged everyday. He felt like a huge support for me during tough days and was always there and genuinely made my day feel better I was the same for him. Got to know for around 1 year.
Unfortunately he began becoming very distant and messaging less. He did tell me a few times he wanted to come off the app and talk on other apps it made me uncomfortable ( due to a past experience)and he respected that. He than come more and more distant and started messaging less until he completely disappeared. It shocked me because I never thought he would go. He told me he was struggling with life etc etc and things were overwhelming him but that he hasn't distanced himself on purpose. It's been around 1 month of no contact.
He once gave me his email address and said if he ever lost contact I should contact him on there. I dont want to be the pushy one etc. But I don't know if I should or not
Any advice?
