Hi just my input I got married six years ago and did so on a budget. I still had the fairy tale wedding but on a lower price scale first I got married on a Sunday that saved 8 dollars a plate. I moved in with my mom to help pay for bills for the wedding since my mom could not give me money. My dad gave me three thousand and that was to pay for whatever everything else was my expense. I was blessed that my MIL worked at a florist so she payed for all the flowers but my FIL and his wife said they would not help at all, I understand that the bride pays for everthing but then when I invited only 60 people and my husband had to invite 150 they should have helped. So anyway only give your son a check for what you can afford
I guess I just don't understand why she would give her son 10 cents to marry this tantrum throwing brat?
I couldn't live with myself knowing I funded a marriage that is going to result in my son being treated poorly

and for how long? or how many times.
It sounds like he's a smart young man and will realize that there is NO RUSH.........slow it down. If she is indeed the right woman for him, she will wait as well. Postpone the wedding......and in the meantime, do a lot of soul searching.
