You change you're mind too frequently for me to trust for a second that you'll stick to that, so what's the point in me commenting on it?
I'll say 'Oh that's good, glad you've decided not to mess her about'
Then a few minutes/hours/days later you'll be posting about how you're going on another date with her and think you might wanna give the relationship thing a go...
Then a little later, you'll go off her again, and then we'll be right back where we are now, with you having more unprotected sex and shirking all ownership of responsibility for the things that happen in your life.
My suggestion?
Start giving a crap.
Is there anything you care about? I'm genuinely curious, because the way you talk makes it seem like there is literally nothing in your life that matters... Which is why you just go a long with things, not really bothering one way or another.
And I'm sure it's all part of depression, and that it all goes hand and hand with drinking too.
I know cause I've been a drunk, and I've let guys use me for sex, and I've had plenty of unprotected sex and even a few times not bothered to take the morning after pill thinking I'd just get an abortion if the worst came to the worse... Which is utterly abhorrent to me now
I was depressed. And depression can make you incredibly selfish/self absorbed. It can make you self destructive, and you can end up taking other people down with you. And it makes it seem like you 'may as well' just do certain things. It creates apathy.
My real advice to you?
Stop dating, sort what's going on inside you out first.
Once you start giving a crap again, then date. And you'll find it's a lot more than this.
