Grow strong during this time BD, and be kind to yourself. Even divorced people reconcile. Remember, the divorce is only a legal signing off of what you are currently living - the separation. Hard as it is, keep doing what you are doing and facing this reality and the idea of letting him go... It's best for now.

I suggest you don't reply to those texts...replying is not No Contact.
If you must reply, say things differently 'under the circumstances, it hurts me - and therefore the baby - to have you at classes and appointments'.

NM, got some better phrasing ideas?
