Does anyone have experience with meth that can shed some insight on why he is now on a online dating site, dressing differently, and hanging out with people I have never seen or met. We were together for two years. He has alienated all of his family and good friends. He has also abandoned his 8 year old daughter. He lies all the time. Why girls on a dating site when he doesn’t have time for us? And he says he loves me very much. Makes no sense. It hurts
I dated a similar guy who is living in a sober living environment for meth and alcohol, and he did cocaine before that. Meth does crazy stuff to one's brain. I had another one just drop me for no reason and block me when he's 6 years in recovery for meth.
He also was on a dating app and said that relationships hurt so much that he just wants FWBs. I had to ask myself why do I want to be with someone like that who hurts me so badly? It's tough to let go, but he's blocked now and I haven't spoken to him since October.
