Venting sorry it's a lot.

So I need to vent and get other people opinion. My on friend just got married this past week and I'm happy for her but also hurt too. I've been friends with her for a little over 8 years or so before she met her husband. At the time I was engaged but ended thing with that guy but still know what kind of stuff I liked she help with stuff. Well when her and her guy got engaged I was her maid of honor and we had already started planning and showed her stuff I had. My ex after the ex fiance who she was friends with to, started tell her and me lies to each other. Pretty much we got in a fight and didn't talk for a year we found out what really happened and we're friends again. I didn't think she'd ask me to be he maid of honor again but she said she wanted me to be in the wedding party still. In the time said said this to when she had her wedding(last Saturday) her and you husband moved like about away to be closer to work totally understand but I would see they were in town hanging out with friends but never even tried to see what I was do just to even say hi. My boyfriend told me he thought that was a little rude but I just brushed it off. It happened more then once. Then I saw her wedding party had their dresses. Her maid of honor was a girl that she told me wasn't a good friend so it made me even more confused. Like if my friend was having a hard time she told me the maid of honor just didn't seem to care too much. Her wedding was over 10 hours away and couldn't afford to go and she know a lot of people wouldn't be able too. The big slap in the face was I saw pictures of it and she used so many of my ideas from decorations to even the whole cakes topper and all. I'm just hurt over all the stuff of not even trying to say hi if she knew she was going to be in town and used so many ideas I showed her. A lot of those ideas I wanted to use for my own wedding. I'll still use them but I feel like she'll think I got them from her. What do you think?
