<human>: So here's your typical /r/relationships post. I have been with this girl for 3 years. We got together by her approaching me, and while I did have a tiny crush on her, I did not expect much from this relationship. Just your typical teenage hook-up. But this one felt different, and later I actually fell in love with her.

I loved her so much that I forgot about anything else: my grades got worse and my friends came to me to say that I'm not spending time with them anymore. I didn't really care. I was happy. This led to me losing two of my friends and really, all of them kinda gave up on me.

She's not the controlling type, she's very outgoing and likes to go out and have fun. I do not. I'd rather stay home, watch a movie, and just cuddle with her. We argued a bit on this topic but we got onto middle ground. Sometimes we go out, sometimes we stay home.

3 months ago we met this girl, we'll call her Julia, through one of her friends. She's like the feminine version of me. We started talking a lot two weeks ago and I developed a huge crush on her. I still love my girlfriend. But it doesn't feel the same. I'm beating myself up for this. She did nothing wrong. I feel like I'm cheating.

So my question for you is, how do I work this out? Try not to talk to Julia? Everytime i spend time with my girlfriend, I'm thinking I'm with Julia. It's eating me from the inside. On the other hand, my relationship with my girlfriend is a very stable one, and if I'm breaking up with her, I will not have many people left in my life, because my friends abandoned me.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Started to lose interest in my girlfriend because of other girl. Friends abandoned me because I did not spend time with them while with my girlfriend. I'm afraid I will lose everyone.
