Input: My ex-wife and I mostly get along ok.  We split custody and after a mess at the beginning we both decided to be really strict about sticking to who has Ely and when.  It just keeps the peace. 

This year my birthday comes up on one of her weeks.  I really can’t imagine not spending it without him, he’s the most important person in the world to me. 

I literally decided to throw a birthday party for the sole purpose of being able to invite them and get to spend some time with him on my birthday without it being awkward .   That was the reason for it.  

I went ahead with some of the plans for it and really didn’t think it would be a big deal, but my gf is furious. I didn’t tell her that this whole party was just an excuse to spend time with my son on a day that’s not mine.  

She’s acting so aggressive about the whole thing.  She wants me to disinvite the ex even though it means that Ely won’t be able to come.   She accused me of wanting to get back together with the ex.   She also said that I was just using her to make ex jealous which is ridiculous.  Her whole attitude could maybe be understandable if we were newly dating, but we’ve been together for over a year.   She doesn’t like ex at all.   But to say “aw well” when I said that Ely won’t be able to come is really bugging me about her.
