Idk how to feel

Ana

I don’t know how feel about my mom getting remarried for the 3rd time. she’s saying the gentleman was send to her from god that this time it’s the right men for her, but I don’t know how to feel they have only been dating for about 3 weeks and he proposed to my mom about a week ago,and I was the last one to find out I don’t know what hurt me more for her to be moving too fast or the last one to find out.

My sister is saying I’m being an ungrateful person by the way I’m acting over this but she doesn’t understand the way I feel and neither do I. Am I wrong to feel this way about my mom being remarried or should I be excited about it and not think about it because it’s her life.
