Soo what y’all think

So ladies I had a miscarriage and my fiancé brother girlfriend acted like she was the best friend there and everything and then I recently told her that I’m going to try for another in 3 months she had a attitude and told me stop rushing to get pregnant and now she has pretty much this jealous kind of demeanor she has a baby of her own so maybe she think Its going to take the attention off the baby she has so we are going on a trip and I’m not in the mood anymore because I don’t deal with a fake person and I can’t help but to think she was fake from the beginning of it all ! And so I told my fiancé that no longer want to go and let’s go on our own trip and he cocked a attitude and told me I always have a problem with people but honestly she the one who has the problem so !..What y’all think ?
