Hi Tubby Buns,
I'm glad you reached out for support. I think your not wanting to bring baggage into your new relationship is a healthy and caring attitude. I can understand your feelings of finding it hard to trust and feel positive again. I can definitely relate, as can, I'm sure, many other members here. You are not alone! It does, indeed, take time to recover.
What kinds of situations evoke your "bad habits" Tubby? Can you give us an example?
Keep posting. We're here to support you.
