Broken up???

So... I've met my exs best friend, it was an accident tho, we met online and realized we live close to each other so we started going out and such, later on we got in a relationship, it's been a month now... I have a problem with touch, I've been abused in the past and I can barely receive a hug without getting all stiff or having a panic attack... he's really helpful and respects it... I love his guys and everything he does, he's really taking it slow and easy knowing my problems.. but... these few days... I feel like its all over... he hasn't been texting me, we had an agreement to meet up and go for a walk but he isn't answering my calls... I tried talking to him and he just says it's nothing... but I can see something is different... yesterday, after school, it was raining, like raining cats and dogs outside and I didn't have an umbrella... I texted him if he could come pick me up cuz I'm gonna get wet and really sick again... all he said was "can't" and left... later I saw he was online but he ignored my texts... I feel like its all over now... and it took me so long to put so much trust in him... 💔😔
