Hi.. sorry I am not up on the DB's stuff

I thought brother because I didn't hear any specific descriptions that gave me that idea. I just thought how nice it was that you and your bro were so close! haha
Okay then! now that I know what we're talking about...
I just want to give a little weeee bit of advisement on a couple of things that flagged for me in your last msg.
I think it's nice you feel that you are there for your bf and you help him with his issues. I think it would be better if you both felt stable in times where you cannot be together/talking every available moment. Perhaps you should give that a little thought. It is great to be able to be so very close, but everyone needs room to grow.
If you feel fear that he may feel desperate and this would cause his eye to wander, then you need to look at this as something that needs attention. A short period of time should not cause him to just move on so quickly!!!
Every relationship has it's trials, mistakes and rough spots. To make a relationship stronger, takes time. I hope it all works out for you.
