God, this sounds like you ripped out the chapter of my life I'm going through right now and created your own story. The only difference between wafts happening with me is I'm in highschool. My girlfriend who's had depression since I started dating her 3 months ago ( same as u ) just started getting much worse, she shut herself off from me, and her friends. She won't talk to me about her pain any more, i thought at first she just list interest in me and almost broke up with me, then she explained how bad it is, and that talking to me got her overwhelmed and she did g know why. She kept telling me she was trying to figure it out but couldn't, I miss her so much and have decided to her therapy myself to get an experts opinion on out situation, I'm not clinically depressed, but I'm showing signs of depression that pass with time, but then get bad when I think of her and miss her. The only times I see/ talk to her now is after school when we walk home, but she's closed herself off up physical contact, we do t hold hands, and when I hug her it's awkward and unwanted/ obesided. Luckily I'm optimistic about therapy because it seems I'm not alone with this issue, ice found others like you and me out there. I'm going to give her the time she needs and hope I get the old her back, I still love her, but it's hard when I get no signs of love, let alone acknowledgement back.
