Girlfriend problems

I have been in my relationship for 10 months, and my partner who has just started therapy, is always using things on me, and I mean even when im upset and telling her how I feel, she will use things on me and shut the convo down.

She never use to be like this, I always validate her feelings or if she’s upset, but with me, I feel like she just doesn’t have the empathy anymore like she use to. She’s only been going for 3 weeks.

I got upset today by something she said, and I voiced it to her, cause I’m a really good communicator like that, and she basically just starts putting me down.

I just feel like I’m not being heard anymore.

She’s changed , I don’t understand how someone at the beginning can show how much they care , to now showing nothing.

I’m legit laying in my bed crying, I got off the phone to her cause I was crying and not once did she ask if I was okay.

I have been in relationships in the past like this and I just can’t put my self through it anymore..

I feel stuck and I feel defeated.

Anyone have any advice for me?
