I don’t know if I should break with my gf

r/

Sorry in advance for my English, it’s not my first language.

Recently I realized I may have feelings for a friend, it happened because she stopped talking to me and i realized how important she really was for me. My principal theory of why she stopped talking to me I s because she also have feelings for me but wants to respect my relationship. (This is a suspicion from about 8 people who interact with both of us and someone’s say she had a crush on me a year ago)

However up to 6 months I’ve been feeling me and my gf have different aspirations in life and she right now don’t have any objectives in her mind, other than being lazy and my gf. Thing that started being a problem for me because my own empathy doesn’t let me talk about it with her cause I’m the only one she has in terms of social interaction and emotional reliance. Despite that, she makes the effort of showing how much she loves me every day and I feel I don’t want to hurt her in any means.

What’s your perspective?
TLDR: I may have feelings for a friend I feel I’m loosing while having a gf.
However i don’t feel good about breaking up because I don’t want to hurt my gf.
