Widowed and second wedding

I was married at 19 to my first husband and had a small backyard wedding that his family put together. We were married for 15 years until his death. I never thought I would marry again but here I am planning a wedding to my wonderful fiancé. We don't want anything big just a small wedding with close friends and family. Since I had hardly any involvement in the planning of my first wedding I've been pretty excited in planning this one. My parents seem to be less than thrilled that I'm having a wedding and not going to the courthouse. I don't understand why they are upset but its putting a damper on my day. They didn't pay a dime of my first wedding and almost didn't show up (I was a stupid just turned 19 year old so I can understand why they were upset about my first wedding). We are paying for this entire wedding ourselves and even though they never contributed to my first wedding I haven't asked them to contribute to this one either. That doesn't stop the remarks they constantly throw my way. The most reason one was my dad telling me yet again that he can't believe I'm having a wedding and not just going to the courthouse. My brother is getting married for the second time as well after a divorce and they seem much more supportive of him. I guess I'm just ranting because I'm hurt. Has anyone else dealt with a similar situation and how did you get through it?
