<human>: My ex and I have been dating for a little over 4 years. Some of the relationship has been long distance. Some has not. It goes back and forth due to his work. These past few months have been, so I've been visiting as much as I can. Probably a few times a month at least. Last week, my boyfriend dumped me via Facebook message. I was really surprised. I begged to let me call him or at least Skype. He refused. He said the relationship was over and he did not want to see me or speak to me on the phone. I even offered to come there so we could talk, which now I realize I shouldn't have done and glad I didn't. His reasoning was that the anti-depressant he's been on made his feelings for me disappear and he doesn't care for me anymore. I asked if it was his depression which he always kind of had. He said no that he always felt semi-depressed but was very happy with me. That it was the medicine.

I still don't know what to think. He's been on this anti-depressant for about 2 years now. We never had any issues other than some moments where he felt unmotivated. He has been trying to come off of it but I haven't seen any real progression or effort. Bottom line, he's still on it. He is slowly trying to come off but it doesn't matter. He doesn't want to be with me anymore.

The only choice I have is to move on and forget about him. I am planning and willing to do so even though it's difficult. But my question is if anyone has dealt with this and what should I expect? If he does come off of it in the next few months, is there any way possible that his feelings for me would return? Is this just an excuse? What do you think happened? We had zero arguments. We always had a great, stable relationship. I don't understand.

Can you give me a shortened version of the text?
<bot>: Boyfriend of 4 years broke up with me due to his medication/depression. Moving on is difficult as I don't understand or know if he will ever come around again.
