Nowin,
Every year, I find myself in a similar "questioning" phase. It's usually the time that I'll make two or three appointments with my old counselor just to talk through what I'm feeling and have him ask me questions. He seems to have a talent for unearthing what it is I'm truly worried about.
You might consider talking through your relationship with your boyfriend with a counselor. If BF has so many problems that you find yourself struggling to not engage with them, then perhaps he is pulling more time/energy/joy from your life than he is adding. I know that I had a helpless, sad place in my stomach when I was making decisions that might bring me closer to my X, and I ignored them as my problem, my issues.
Really, what was happening was that my heart was telling me it wasn't the right thing to do - but I didn't listen. Ponder carefully why you're doing what you're doing and be sure there isn't something your heart is trying to tell you.
Also, I find that as I get older, it becomes more of an effort to make and keep friends. Everyone is so busy with their own lives, etc. I have to make an effort to get out, take night classes/workshops, engage in my community's activities, and things like that in order to feel not-isolated. It is worth it to me. But when I was tangled up in my X's life, it was very hard to get out. I slid further and further into isolation with him and another codependent cycle.
Just some thoughts that came to mind from my own life. They may or may not apply to you.
Listen to your heart and find ways to give it what it needs.
