My very best friend got really mad at me today because she is having a birthday dinner on my boyfriend’s birthday. I know I’m prone to abandoning plans with my friends because of going out (or should I say, staying in) with him, but this is his birthday and I wanna spend it with him. Her birthday is on a different day, she is just celebrating it on the same day of his birthday. I offered to take her out for dinner another day and I do understand where the anger is coming from, because we recently became medical interns and we don’t have much time to do anything outside the hospital. But this has happened several times before, and I feel like she is trying to make me feel guilty for not spending time with her. This has happened several times and every time it happens I always apologize because I’m afraid she’ll stop talking to me, because she is one of my only friends. This time I feel like I don’t owe her an apology but at the same time I think she will stop talking to me. What should I do?
