<human>: I've been dating the same girl for about a year and a half. At this point, I can still say truthfully that I love her, but we have been distant, in part because she is finishing up her last year(ish) of school, and I am already working in the city. We see each other once every 2-3 weeks.

However, there is another girl at my work who I have known for some time, that I am starting to develop feelings for, although I have never cheated on my gf with her.
Here is the kicker. My gf is going to study abroad for her final semester (4 months), and the non gf "friend" is moving away in August.

I feel like I am losing some very important people in my life, and there is nothing I can do. I really feel like I can't tell either girl the extent of the situation, because then I risk losing them both entirely.
Another issue is my pot use. I find that it helps with my depression, which I think is in part caused by the fairly consistent lack of female contact, and no means to get it without cheating. I normally like smoking, but I want to save the money instead.

I've told my gf that I need a break this fall, as I can't do 4-5 months of NO female contact whatsoever. She was upset, but asked if we could still keep in contact and I was thrilled and said of course.
I just feel really confused. Just typing this sort of helped, but I'm scared that I am going to lose people I care about.

Can you provide a brief overview of the text?
<bot>: I have a gf and a "friend" that I have feelings for, and will probably lose them both and I turn to drugs to cope.
