Do keep in mind, I am much too nice of a person, but sometimes that can be a good thing.
I got into contact with him a couple nights ago. Considering how big of a no-no people deem that to be, I don't regret it. He asked me if I was happy with the guy I'm going after, and I told him if I wasn't, I wouldn't have gone with him. He started telling me how much he missed me, how he just wants to drink his problems away, how he's accepted that he's a liar and a cheater. And you know what? I wasn't okay with that. I don't care who you are, enemy, ex, whatever, I won't stand to see someone waste their life away like that. So I told him I called bullshit on it. I told him not to let some girl he hasn't actually met yet completely destroy his life. I told him I refuse to accept that he's accepted that about himself, that he should, instead of sitting around, get out, go on walks, work out.
I told him he needs to better himself. He agreed. So yesterday he went out and ran a few miles. And you know what? He feels so much better. He's been doing a lot better since that discussion with him.
So I don't regret breaking the "no contact" rule.
