Finally stick to my boundaries and now feel guilty…

I’ve been in Al-Anon and therapy for two years and I have been working hard on myself. My AH of 13 years crossed two boundaries yesterday which are drinking and driving and lying about it. For the first time ever I stuck to my guns and asked him to pack enough stuff to go stay at his dads for a few weeks. It’s only the second night and I already miss him so much and want to ask him to come back. I haven’t told him this just posting here bc I know I shouldn’t cave in or I will be bluffing yet again. Just a little backstory he has two dui and my trust has been ruined due to the lies he tells About drinking. He has hurt me more times than I can count. I’m feeling weak for already wanting him back.
