Thank you genn and happy101. I talked to T today about my friend and boundaries but left out the part about wanting T to abuse me/cross boundries

In short she said that as long as I'm willing to try and in fact do set boundaries for my friend than I should be ok. If I do set a boundary with my friend and she continually crosses it without any regard than I need to not be in that friendship. My friend in general is supportive and doesn't intentionally cross boundaries as she's just really good at asking for what she wants (something I have a hard time doing as I'm a people pleaser).

happy101 thank you for the book recommendation. I'll be sure to check it out!
