Op I’m so sorry that you have been deceived by this awful man. It sounds like he targeted you for money and other reasons? Sometimes men behave like this just because they can. They take pleasure in the deception and control. He is utterly toxic.
Block him everywhere and step away from any association with him in every way possible; in your mind, your emotions, on social media, and never physically meet him again. Does he have a door key to your house? If so, change the locks immediately.
He is dangerous in that he is a good manipulator and plays with women’s emotions in an utterly callous way. He is doing the same right now to this other woman so please do not envy her! You have escaped his clutches and in time you will come to see that that is a very good thing.
How much debt did he build up on your credit card op? How much have you been left to pay?
Be careful because he might try and get back in touch with you when he is short of money again.
Is there any chance you could sell his guitar to pay some of the debt off?
As an older woman with young adult daughters, your opening post really distressed me but this in particular;
“This evening work got more frequent and by March I found he was seeing someone else. Stupidly I didn't end it and we kept working. Unfortunately, a month later it was found he was still seeing her. He blocked her but four days later he broke up with me. I was devastated and begged for another chance.
The day after we broke up he said we could try again and work toward getting back together. Things became more normal but he had to have 'space' Friday nights.”
So within that one paragraph he deceived you so many times and each time you forgave him and wanted him back? This made me want to shout at the screen and feel so distressed for you all at the same time!
I know you now know that you should have kicked him to the kerb in March, or before that, but why are you accepting such poor standards for yourself?
What were the male role models in your life doing that made you feel so unworthy of love and respect and decent treatment? 😪😘
Please, please op, if you were my daughter I would ask you to stand in front of the bathroom mirror and repeat the words;
”I will NOT enter in to another relationship until I have worked on myself, attended therapy, started to love and respect myself, and feel that I am worthy of love and respect by someone else, and I will not accept any invitations from men who drink, have mh problems, or money problems.”
Reading between the lines, you sound like a lovely, caring supportive person and people take advantage of that. You do realise that this malicious man probably wound you in with tales of his schizophrenia. It all sounds very calculated to me,
Op please take care of yourself and protect your boundaries. You deserve so much better. It’s far better to live alone on your own terms than lower your standards 💐
