I asked H to leave; regret-now what?

[Luluber1]

Thank you for your comments. Voicemails and e-mails are not working.I did send him a letter (email) of apology acknowleding my own faults and that I regretted the overreaction of asking him to leave; I could have responded to his actions a different way and still set a boundary. In my last voicemail, yesterday, I did discuss the bills calmly and said I understood that he was angry at me but we needed to discuss these bills.He has not contacted me since separation.

I'm thinking of sending a certified letter to him discussing the bill and the "lets talk." If I go to his place (his dad's house) he will construe that as "drama" and I doubt that will go well. I did think of another option and that is to borrow money from my mom but I think she will eventually tell my H and lecture him about responsibilities. I don't know if it's a good idea to get relatives involved. Any suggestions on the certified mail or loan request options. Thank you.
PS> I have read a book "Hope for the Separated" by Gary Chapman that has been a great help to me and would recommend it to others; it has taken the "panic" from me and helped me work on myself.
