I'm going to end a 7 year friendship over a guy
Why are you ending a 7-year friendship over a guy?
They don't get along and I'm in love
Sometimes if people don't get along you might have to make a choice between them. If you are in love, it makes sense you would choose that person over your friend.
She just got in the way
It's fine to choose a love interest over a friend if you think that you and your love interest both feel the same way for each other. If not, you may ruin a great friendship over something that doesn't have long-term potential.
