Unenthusiastic bridesmaids - having doubts about who i asked. Please help!

Okay, so last weekend my bridesmaids and I had our first makeup and hair trial. It took (literally) months to organise as my 2 bridesmaids would not answer my messages or get back to me. Eventually we all settled on a date and I organised everything. I picked my friends up and brought then to my house. Neither of them said thank you and when we started talking about plans for the big day including dresses for them, the food, the schedule, one of them was sat arms crossed and didn't say anything other than "I don't like that" or "that colour isnt right". There was nothing constructive or helpful at all. My other bridesmaid took some notes and asked some questions but that was it. When I asked them about dresses, they both picked the same one. I wasn't really pleased as I wanted to go for mismatched dresses - how do I speak to them about this?

After a little more coaxing of answers from them and asking them for their help setting some decor up the day before, the makeup lady arrived. We all had our hair done then our makeup done.

All afternoon I offered drinks and food and if they were all comfy or needed anything. They refused all refreshment and when it got to late afternoon, one of my bridesmaids stood up and said "I'm going now". Her new boyfriend of 8 wks was picking her up. I had no knowledge of this as we had planned to have a late evening of drinks and take-out. I was very disappointed. Then my other bridesmaid said to me "can you text my ex and ask him to drop the kids off here as this is taking longer than I thought. Make sure you say I'm miserable though otherwise he will be annoyed with me". I couldn't believe it. I felt like I was being dropped. I had been so stressed and worried about the day as I needed to talk to them about so much, but they didn't seem to care. I felt as though neither of them wanted to be there or could muster any enthusiasm. I am still feeling hurt today, and I don't know what to do.
I understand they have their own lives but all I asked was for a few hours. They had plenty of time to organise everything.
Please if anyone can advise it would be much appreciated.Katie x
