Should I give this Baby Shower Help me please with advice.?

I asked a friend could I give her a baby shower, her reply to me was yes I can. I did not realize she wanted it to be very very extravagant. I told her and her family up front the shower would be nice but my money is only limited. I told them what I was going to serve and how I was going to set things up; They came to me and told me how they wanted it to be done and the way they want it will cost me hundreds of dollars. I told them again my money is limited, I just had a new baby myself. They began to go out and buy their own food and setting they bought their own games they want to play they have almost took it out of my hands; then they told one of our friends I do things cheap. I thought when you give a person a baby shower you buy everything and do everything for their shower; the person who you are giving it for is not suppose to buy everything and then take it over and say to me, you just stick to being over playing the games, I am offended am I right or wrong? Someone told me the person you are giving the baby shower for can tell you what they want the shower to look like and what they want to eat, I did not know that! she wants a table to be spread for a queen, I was going to do a simple meal she wants this lavish meal, I thought they just come and be honored, the shower is in four weeks the invitations have not been sent out because they say their going out and buy some more prettier invitation to send out because they do not like the ones I bought, no Mine are not $15.00 invitations but they are not cheap either. I am hurt I do not want to give this baby shower they have called all my people who was going to help me give the shower and put their own friends in, my helper are hurt too; now they are going around telling people they are giving their own baby shower because I do things tacky. Should I not have anything else to do with it even though I said I would give it, is it proper to take my hands off now at this late date? I've already bought some spagehetti and the sauce and chicken wings and they told others if I bring spagehetti to the shower they are going to throw it in the garabage. What should I do to save face, and keep peace, I do not even want to come to the baby shower now. Am I wrong? I heard, The young lady and her family is telling people, how can they remove me and take it over and do it right, I have always gave baby showers, parties ect.. and I will admit I does, do things in an economic way but it does not be tacky to me! others have said I do a nice job at giving my parties, I feel I am just not high cl enough for these people, I do not have hundreds and thousands of dollars to throw this function.
