Having private conversations online with the opposite sex: Heartbreak City

Recently I've had women cut off online private conversations for:

1. Claiming I'm not trustworthy when they lied like crazy to me.

2. Thinking I was chatting with them because of "ulterior motives" when there was no evidence for that.

3. Using a persona to post on an online forum when everyone does that. Everyone posts using a persona on a forum unless they're openly reavealing who they are.

I'm starting to think there's no point in even trying anymore.

Anyone have advice?

Here's my advice:

Never mention another woman to the woman you're chatting with. Even if the woman you're chatting with is married, they seem to look at any private communications with a man as being like a date. And, they want your full attention. They want to pretend it's just you and them...on a date.
