Welcome, Human_behavior!
Just wanted to pop in to join
Wentworth in welcoming you to the forums. I'm sorry for what you're going through but glad you have found a community where many of us have been through similar experiences, and we can learn from each other. I wish for you as much help and support as I have received.
Thank you for what you have shared with us thus far:
The night before he was so sweet and loving. Now this? Anyone else experience anything similar? Or can shed any light? I could rationalize this in my head over and over, but hearing it from someone else really helps sometimes.
I think by reading some of the discussion threads here you will find that this type of behavior is, unfortunately, all too common. We all been there to varying degrees and can really understand where you are coming from. So... .what I'm hearing from you is that you are confused at this abrupt change in behavior. Is this the first time your boyfriend has acted this way? Is there anything that you plan to do to address it?
Have you seen some of the material located in the right-handed panel? The site articles can help you make sense of what just happened at your boyfriend's house.
I'm sorry you're having a tough time, but we're so glad you're here. Keep reading and posting, and I'm sure you'll get help and support you need (as I have).
Keep writing, keep processing, keep learning!
