eloping and having a larger celebration down the road

So my FI and I decided after months of crying and fighting with our families over all the details who's paying for what, whether or not we should be married, mean things being said to us and about our decisions to marry we are eloping. So I must add before anyone leaves not so nice comments like I've seen on other posts about eloping. We are going to announce to our families after the elopement takes place what we have done, and we already know his side wants to see us be married so we will in a year or two when we can afford it on our own to have a wedding for everyone to attend.
