I am not sure if its just me, or what.
My boyfriend is wonderful to me, his kids and I and his ex get along great.
But I broke up with him, because he hugged his ex-wife goodbye when we went to get the kids. I am not sure why I got so pissed. I just did.
He also when telling the kids goodbye every night on the phone, he always talks to her last and has to make sure to say I Love Y'all.
Whats up with that.
Isn't that disrespectful?
Or am I just reading into it too much?
