Yep, I'm taking it personally. Why? Because it's stigma and there has been support for that stigma shown in this thread, beyond the OP, that are in agreement with the stigma.

I take that personally. I do not deserve to have labels like untrustworthy, a burden, being abnormal, having trouble with a traditional relationship, etc being said.

The girl the OP is talking about has not done to deserve having her honesty and trust questioned. She has not demonstrated anything that would make her a burden. She has not demonstrated anything showing that she doesn't want a traditional relationship.

In fact what we see of her in the OP is the opposite. She has been honest with him. She is responsible for herself and not a burden. She has consistently expressed wanting a relationship with the OP.

And yet people are still condoning the questioning of her honesty and trustworthiness, and are concerned for the OP being hurt when he is the only one of the two to do anything hurtful.

That is why I am taking it personally. The behaviour and personality of this woman (from the OP!) shows her to be the exact opposite of what the OP fears, and various posters have been agreeing with his fears and their validity.

By that logic, it means that simply having bipolar makes someone untrustworthy, a burden, and not capable of commited relationships. I am none of those things and it isn't something I'm willing to just sit around and let slide - based on the information the OP has provided for us it is the woman who should be having our sympathies as the OP has been in the wrong.
