I don't know what to do

I met my boyfriend four months ago, we immediatly fell in love, it was all perfect up until this moment – I had a tough times exepting myself as trans and only recently I finally started believing that I deserve a happy life.

Unfortunately, a month ago things started to change. My boyfriends started working a lot (I really mean in, with no weekends) because we were planing to move to another country. There were times, when he was working during our dates. I told him, that he won't make it like this, but he didn't listen. A couple of weeks ago, he told me, that he does not feel anything and became very fatigued, I said, that it is probably from tiredness, but he said he can't work less at the moment.

Then last night we had a date, and he seemed really down, I also notised that he did not tell me "I love you" for a couple of days (in the recent past we used to say it to each other everyday) I asked him if everything is alright between us. He did not respond. I asked him again, and he just burst out crying, saying that he lost all feelings he ever had to anything, and now he thinks he loves me "with his brain, but not with his heart". I made him promise to arrange at least one day-off per week for himself, with no job and no classes, and he told me, he will do it. He also kept repiting how guilty he feels, because he knows, he caused me pain, but he has no energy for romantic relationship right now, yet he said he doesn't want to end things. I told him, that everything is fine, and he must not worry about me. But I was not fine, I felt horrible.

I gave him a contact of my psychiatrist, in case he ever dicides to get some professional help, he huged me, we kissed and I left.

Honestly, I don't know what to do. I don't understand him. Maybe it's just because I am autistic. Though later on he told me he doesn't understand his actions himself.

I feel so horrible, everything was perfect at first, and now I don't even know if we are together or not.

Please, give me some advice.
