Wow, that was a great response!
I am totally that person that constantly needs affirmation. Everything that you said you always wanted/needed to hear I want/need to hear too. I have been careful not to let this side of me show too much in my current relationship because I don't want to be THAT kind of guy. The fact of the matter, however, is that I sort of am.
What got me was that my boyfriend said all those things and sent all those texts constantly at the beginning of our relationship and I ate it all up. As the relationship progressed, however, this changed and that's when my perceived problems began.
As far as whether or not my boyfriend is emotionally distant, I definitely wouldn't say that he's cold-hearted or anything like that, but I sometimes feel that there are certain barriers that my boyfriend has that can't be penetrated. You said it perfectly. And yet, he didn't always seem that way when we first started dating.
As you said, it's finding this balance that I need to work on because the whole thing is driving me nuts, and I'm the type of person who perseverates on something always trying to find the solution.
Thanks again for your input PowerFade, it is really appreciated!
