I'm going to choose to spend time with my friends and  boyfriend rather than my family
You can't find the time to spend your time with all of them?
No, I simply feel incompatible with them and don't want to spend time with them.
Your family is not always compatible with you, this is a fact. Spending time with everyone (family, friends and boyfriend) is best and it may really hurt one of them to be left out of your life completely.
That sounds like a good idea but I don't feel like it.
That's fair, you don't need to feel like it. Just know that they are probably hurting if you never spend time with them, and it would be cool of you to give them a few hours every couple of weeks just to feel like they're in your life still.
