Ok that's something at least, there will probably be a time when he tries again to slither back in. Please try your best to remember your worth!
I was with someone from 15 to late 20s, literally grew up together knew nothing but him. Thought we were 100% solid and although some of my friends and family didn't think much of him, I knew him better than anyone and we were absolutely forever. We broke up a couple of times and he saw other people but I didn't. I was convinced I was the only one who really understood him and all that meant he would never hurt me...right?
I felt so stupid when it all came crashing down. I couldn't do anything, lost loads of weight, ended up having to leave my job as I couldnt cope.
Even after he married the other woman he still tried to pursue me. Followed me, randomly call me trying to meet (before blocking was a thing)
My whole identify was wrapped up in him and I'm not going to lie it took a long while for the gut punch feeling to go. Constantly feeling sad for the life I was supposed to have with him, all my childhood/teenage/early adult memories tied to him, obsessed with how it ended and how he could have been so cruel.
When I think of this person now, he absolutely makes my flesh crawl. I can't tell you how lucky I was to get out without marrying or having children with him. He cheated on his wife (the OW) left her with 2 children and went on to have more kids with different woman. I imagine the same is happening with this person.
I now have a relationship and family I wouldn't have even dreamt of back then, I'm so grateful.
It stings like an absolute mofo, you won't be able to get out of bed some days, some days you'll just stare at the wall but one day you will wake up and it will hurt a little less. You may not even notice, you'll go for more than an hour without the sharp intake of breath, the racing heart. I'm rambling but I know exactly where you're at.
Be kind to yourself, you've had a massive shock. It's going to be shit for a bit. Keep talking (here and in real life)
