Welcome, Catperson!

I wanted to take a moment to welcome you to the discussion forums. I'm so 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. From what you have written, it seems clear you will get good ideas and support here if you continue to read and post. In short, you have found the best place in the world for understanding, compassion, and education as it relates to coping with loved ones who have personality disorders.
Thank you for sharing with us what you have thus far:
But i always have the sense that things can just fall apart at any moment. We dont live together and i have a lot of fears about moving in. I’m not ready to take that step at all but i fear that her family will start applying pressure soon. They really like me a lot and have been very welcoming to me. My girlfriend has had many bad boyfriends in the past so they see me as a breath of fresh air.
I hear you, friend, and understand this well. Is it possible for you to see this family pressure as being
outside of the decision-making process? In other words, any decision you make regarding your intentional involvement in escalating a personal relationship should be 100% yours.
Sometimes i feel good about things and the relationship feels good, and then other times i just want to get out so bad. I just dont know what to do.
I am so sorry you are faced with this. Even so, I just have to applaud you for being willing to continue to put forth effort into understanding your SO. In my opinion, that's a start. This site is rather HUGE, however, there are many, many articles related to bettering your relationship with the angle of using healthy communication techniques, setting needed boundaries, and validating what is valid. You will find these articles in the right-handed panel on this board. We can help you with questions, point you in the direction of additional resources, or just be a sounding board.
Tell us more about yourself and your story. It helps you to get it out, and it helps others when they see that they are not the only ones suffering. We look forward to hearing more from you.
Keep writing, keep processing, keep learning!
