Oh well that changes everything!
I hate social media, too, for privacy reasons. Maybe this sounds weird, but I won't get involved with someone who has a need to plaster their life online. Don't get me wrong, I know many people use social media responsibly, rather it's the ones who feel the need to display all aspects of their life that I can't handle. It has brought unwanted drama into my life before.
However, this site is different. While no site is 100% anonymous, there is indeed a higher level of anonymity here. You can keep it that way by telling no one you come here. (Nobody in my life knows I'm a myptsd member), not posting personal details, not leaving browsers open, clearing your history, etc.
Future partner? He will never know of my presence here. I won't take the risk of letting someone use all that I post against me.
For me, it's not about lying. 100% transparency is not something I desire in a relationship as everyone deserves to have private parts about themselves. This is a private part of me.
