Being Emotionally Dependent

It's been a few days, and things have gone exactly the way they should. The ex I mentioned is no longer in my life, and I'm keeping it that way. My roommate's love life has taken off, so we're going to be in a bit of a role reversal for a while. Yes, I'll still be talking to guys and looking for the right person, but it's never going to be like it was. It's going to take me a while before I fall hard for someone.
Funny story: not 10 minutes after I saw my ex for the last time to pick up my scarf from him, I got a text from a guy friend telling me how much he missed me. We will call him "M" for now. Well, M and I met at a conference out of town almost 2 years ago. We had an amazing night together the last night of the conference. Danced the night away and tried to sneak off, but my amazing friends wouldn't let me out of their sight. At the end of the night, we exchanged phone numbers and have been talking ever since. There has always been a high level of attraction in our friendship. We have gotten to know each other on a personal level through music and sports mostly.
Well, during my crazy 3-week period this late November/early December, he came for a visit. We had fun just like I knew we would, but there was something more. We were able to really open up to each other about our lives. After he went home, I didn't hear much from him until the other night. He told me that he thought about me a lot and wanted to be someone I could rely on. I am so thankful to have him for that! It's one of those things you don't expect someone to say, but when they do, it means the world to you. I'm trying to talk him in to another visit soon. I love having him here.
I know you're thinking, "SL, put the brakes on! Why do you constantly need to have a guy in your life?" Well, to be honest, I just don't do well on my own. I'm emotionally dependent in that department. It would do more harm than good for me to try and change. I am ok with the consequences of heartbreak and such.
To leave on some closing note, I'm excited to live my life in this state: rejoicing in the triumphs of others' relationships and enjoying what I can in my own life.
