She's going out of my mind
We used to be pretty close, until the baby came along. Now for the past 5 years she tries to avoid intimate contact whenever possible. Always some excuse or another. I have dropped many not-so-subtle hints that she needs to get her hormones checked or something.
Now after 5 years I'm finding that I'M not interested in HER any more either. And I've cheated on her twice recently. Part of me feels bad about it but I also feel like she's mainly to blame. I could fall back on the "Guys have needs" excuse but I think I really have just been doing it out of spite. And now I'm starting to feel like I enjoy this kind of arrangement better.
