Dear allme, I am so sorry you are feeling this pain. No surprise it has flipped your mood into a place of sadness. I pray somehow it can be resolved between you all. Please try not to feel badly about yourself. This is her problem not yours. Seems to me the boyfriend with whom you have had the longer relationship is the one on the spot to work this out. Him putting the blame all on you is totally not fair. Her immaturity is showing. Their relationship is sounding a little rocky to me. Sounds like they are avoiding a bigger issue and using you to avoid it.

Give it time. Don't own her stuff and refuse to let it get you down. I know. Easier said then done but it really is a waste of valueable energy to beat yourself up about something that has nothing to do with you. No one is perfect but don't add insult to injury by owning something that doesn't belong to you.

Give a big hug to hubby for standing up for you and hang on to each other while this storm passes. This too shall pass. Don't let this little girl bring you down. Pick yourself up and let her self distruct all by herself.
