It makes lots of sense. I was talking about it on my thread just a few days ago!
I think that the number one thing that you can do to detach is stop contacting him, stop checking on him, stop constantly worrying about what hes doing and who hes doing it with. And of course, getting out and doing some things for yourself! The less contact you have with him, the better you will feel.
I think that the anger is totally normal too. Dont feel bad about it, just let it pass. And I absolutely beleive that he notices. They notice everything!
So, its almost wednesday, do you have some friends that you could plan a night out with? Fun, just you and your friends, get a babysitter for the baby and let yourself have some fun.
Get dressed up and let the hotties look ogle you!
I guess I gave the wrong finger to the wrong man...
