Drama with friends :/

So I'm 21 pregnant (31weeks)with mine an my husbands first(: well anyways I was messaged by an old friend from high school tonight an she told me some things that were extremely hurtful. She told me that someone I thought was my friend was saying all these terrible things about me an my pregnancy an my marriage. I guess this supposive friend of mine said that I lied about a chemical miscarriage I had back when I was 19 with my husband when we were only engaged. Then she went on to say how I was going to be a terrible mother and how she deserves another child over me. Btw this supposive friend of mine just turned 20. She has a son that will be one this year an is married to a marine. He got deployed early last year and she was hoping to be pregnant before he left so they would get more money while he was deployed. I'm not saying this out of assuming, this is something she actually told me herself. But I guess she just was going on an on about how because she married a military man that she deserves more is better than those of us who didn't marry into the military. Aparently my husband an I are white trash because he's a professional painter and we live in Maine. I'm not sure how that makes us white trash ? I just don't understand what can make someone say such hateful things when I honestly thought we were friends. I've known her since she was 14. But I guess because her husband could buy her a house an brand new car makes her better than us. Because we rent our home and drive a 2000 we are just poor people that won't be able to take care of a child. I don't understand the logic in this. I'm just super hormonal an upset over this situation. There are things about her and her marriage an how she parents her child that are just out right terrible but then I'd be no better than she is by bad mouthing her. But the things she says about me just doesnt make any sense.
