you're not lacking in tact babe! if you were, would you have come in here and asked how to deal with the situation - i think not!

FWIW - there is probably lots of little stuff that, on it's own, means nothing - but all together, have just made your friendship "too hard" - so you work through it now and make a go of it if you can - that's how it is. if she is hung up on things like you hanging out with her ex (in any way) when he was her EX then her issues are deep and might not be about you at all - possibly you're jus thte one she's rejecting - to a degree - because of it.

chin up babe!
