She is a nice caring sweet woman an I guess men take advantage of her. I try and explain that unfortunately when she is seeing these men she has to be less available or not as nice. She said there is no way she can b this way. It’s unfortunate but true in most cases. She gets frustrated with my advice because I get so angry I can’t help it. I feel her standards r so low sometimes. I guess it’s cuz she’s gettingolder and all she’s ever met are assholes. I’m hooking her up next week with my friend whose a great guy. Hopefully it’ll wrk out. She’s always down in the dumps and depressed. What advice should I give her? It’s like the last guy she dated was a dick and she just constantly blames herself but it’s really not her fault. I wish I can get her to see that but with all these relationships not working out she is starting to think it is her.
