NM, I don't think that it would be out of line for you to remind him that if he wants your texts, love, etc., then he knows what he can do. It's not up to you to take care of his emotional needs right now, because he's decided to get his needs met elsewhere. As long as you say this in a loving way, then it's not b!tchy. B!tchy is not the opposite of distancing; it's the opposite of loving.
I also think that GAL helps here. IMO, you are still trying to meet to many of your needs through him (not that I don't have the same problem), and you need to find ways to meet more of your emotional needs in other ways.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
