Any tips to deal with Jealousy on my part

[g450]

Well I heard her talking to a guy last night for over an hour.
She was only talking about the football game that was on her TV though.

I heard the whole thing and did not hear anything disparaging.
Perhaps my fears are unfounded.

Still though, over an hour on the phone with another guy. That really botheres me.

I know who this guy is because she said his last name. He went to high school with her and is one of her facebook buddies. I even found a photo of him on classmates.com. It appears that he is or was married and has children (probably grown by now).

Listening to her last night made me feel ill. I remember when she used to talk to me like that. Havent heard that sweet tone of voice form her in years. When she talks to me her demeanor is short and too the point. Almost like she is pissed-off at me 100% of the time. I hate this.
