Do I Go To My Cousins Wedding In Jackson hole

My cousin is getting married in Jackson Hole. My husband is unable to go because he is working and I can still go and bring my baby. Here are the thoughts I’m having: I don’t want to go to Jackson without my husband and toddler. My cousin and I aren’t that close any more. My parents and aunt and sister are going to think I’m selfish for not going. I am selfish for not going. She wouldn’t do the same for me. My feelings from those thoughts are guilt and resistance. I also have other thoughts like: it could be exciting to go.
