Did I do something bad?

Okay... so I am on vacation with my family, which is hard because that means that I am away from my SO. Today my aunt and my grandma went to get a massage (they were treating) and I wanted to go with them because today was the last day for my to go (I don't have money to afford it on my own). Wel when I called the spa, they only had one appointment at the same time, and it was with a Male. 
I texted my SO and asked if he would be upset if I went, but he didn't text back, so I thought about it, and decided that I would not be upset if he had a massage from a woman, because I knew that it would be strictly professional. So I took the appointment and went, and when I got out, he sent me a text just saying "it's whatever, have fun" and when I asked him if he was upset he just said that he was and that he would text me after he cooled off.
Should I feel bad about getting the massage? I know his anger is justified, but it is not worth breaking up with me, right? 
I put please, or other personal stories?
