Ophelia, you need to take a breath and stop all this drama. it does NOTHING to further your GOALS for this M.
Yes, your H is being a selfish jacka$$. Look around these message boards. There are TONS of them treating the spouse like yesterday's news. You being a stark raving b*tch and involving his mother is not good for long-term goals here.
STOP texting him. STOP calling him ad nauseum. LET him go. You are being clinging and off-putting with this behavior. I COMPLETELY UNDERSTAND your emotions. I DO. My H also had an affair. But you have to step away from this and stop stirring the pot. Get to counseling just to have a place to vent in person. vent here. do NOT vent in real life like you have been.
somebody else should step in here if they disagree with me, but you are spiraling this thing into a cauldron of a mess. of course this is JMO, but i am worried you will do irrepairable damage with all this anger and drama in a public forum, and with his mother as well.
Forget the former things; do not dwell on the past. See, I am doing a new thing! Is 43:18-19
If it seems slow in coming, wait. It's on its way. It will come right on time. Hab 2:3
