With all due respect, hell no. Too many issues. Usually when someone has that many issues, there's no way their problems won't overflow into the relationship and sometimes begin to dominate the relationship. The whole relationship revolves around their issues; what mood they are, keeping them stable, keeping them functional. It's truly tiring and it's frustrating when you just want to know for sure that you are going to have a great night or enjoy an awesome vacation you've planned without it being tainted by one of those issues.
Yes i would. Theyre probably hard things to endure. Having someone to joke around and laugh so she's not alone [where she would otherwise revert back] would likely help if not cancel out her need to do those things.
