A brief explanation, Sorry it is long. DP of 33 years, 2 teenage DC, is pushing 70. Looks a little younger than his age, but pretty jowly. Is an artist, musician, not very successful but comes across as bold, passionate, energetic. So about a year ago I linked him up with someone I had known for 2 years because she could help him with some printing up of artwork. She was then 27. After a few weeks, it turns out she tells him she has the hots for him. He tells me because he was so surprised. I think wtf but assume it is an aberration, the end of it. But I spy on his emails, because I am mistrustful and I see him online a lot. Yes, bad I know. They meet up a bit to play music, usually with others, so I start going along. They exchange a lot of pornographic drawings by email and he idealises her in poems and she writes saucy language about him opening her up in mind and body. Yuck. I eventually come clean about spying, go mad, tell others in the group what has been happening etc.Ban him from seeing her. He complies after a lot of arguing and him being nasty and talking about opening up our relationship and me saying no way. It has been a shitty year since with him drinking more and more and me getting paranoid and upset. I won't go into how crap I feel and how broken, because he said things to her about me that are wounding. I just want insight into her. Now 28, I suppose. Occasionally she has sent a letter, which on one occasion he showed me, because he couldn't work out who had sent it. It was all punning language about hearing him on radio and feeling held in his hands, blah blah. We saw her at an event last week. Today she sends an email saying she must see him and she will knock at door at 1pm. He tells her no and she stays away. What is this about? Is he really a catch for a young woman? Is she trying to destroy me, for fun, as she is well aware how shattered I have been through all this? Any insights?
