Why does she feel this way?

My mum seems to be not encouraging about my current bf. I mean I've had a childhood boyfriend who she wasn't encouraging about. And then I had an abusive boyfriend from 15-17. I hid him from her but eventually it came out and she was so disapproving and encouraged me to break up with him.

Now I'm 19 and I have a boyfriend from uni who treats me like a princess and I tell my mum about him, and the first thing she says is 'but what about Timmy??' Then laughs nervously. (My childhood boyfriend- who was a Christian and nice I guess). Then she asked a load of questions, is he nice, is he a Christian etc but she looked so disappointed. She looked so uncomfortable. And then I noticed she was weird and I think I said something like I really like him and she said 'I just don't want you to get hurt'. It made me feel worried myself. The whole reaction was so negative, nothing nice she said. This happened like a month ago.

Anyway today she text me saying she loves me and asked me how I am. I said I'm good and I've been hanging out with my boyfriend. I ask her how she is. And she completely ignores me.

I'm so upset, I don't understand why she doesn't like him and isn't saying anything nice, she's never met him!!
Im scared she's thinking it's not right (he's not the one for me by god) but I really like him and I thought God told me he's the one, I literally prayed to find the one a few days before I met him. I told her that.
