shall i break up with my bf?

he is such a lovely person and i’ve communicated to him how i feel and even said how he would try make me feel better about how i feel but i just feel so selfish to not provide him with what he wants

You're not selfish, and I think it shows that from you already communicating with him how he feels. However, it does sound like the relationship itself is not fulfilling you, and that's not a bad thing to realise for yourself. I can understand it must be hard to be trying to process all of this but I do think you need to put yourself first. I think in the long run you are just hurting yourself and him more. Maybe it's good to wait until you can both be together in person and see how you feel. I'm also doing long distance rn and I know communication and feelings can be difficult at times.

I feel like i’ll enjoy being with him when I am with him, however it’s just when I leave again i’m afraid i’ll go back to feeling the same way about him. Thank you for your advice x
