Am I wrong for feeling this way???

My husband and his mother has not had the greatest relationships. They didnt talk for a year and it was not until I sent her a wedding invite last year that they begun speaking again. Which is great I want my husband to have his mom in his life. my only problem is I feel like she is selfish. My reasons being is that for the last 10+ years she has not step a foot past her front yard. She had claim to get panic attack whenever she entered the car since a previous bad car accident. Because of this along with other things a 20 year relationship with my husbands step father ended the begining of this year. Since then she has found someone new. For this man she has known for less than a few month she has been leaving her house and such.

Going to birthday parties and events for this new guys family. Now what bothers me is that she did not make it to my wedding last year because of this fear shes had. She refused to even try even though I chose to get a venue close enough to where she lived so she wouldnt have to travel far! She is supposedly going to marry this guy in July (which iabthe same month I got married)and asked my husband to give her away. When I found out I started to cry. One because I feel like if its so easy for her to change now why didnt she just face her fears to support us on our big day? and two because I feel like she has never offically given us her support or blessing but she wants us to give her ours. Am I wrong for feeling like this? I knew her not making it bothered me but i didnt know how much until I cried today. My husband not so much because he is used to it, she has never shown up for any major milestones in his life not High school or college grad and now not wven his wedding!!! Ugh😡
