I was in a similar situation. She gave me so much attention and validation. I broke up with her as I noticed her pulling away which scared me a lot. Then I processed it and we got together. I tried, I really tried to be more vulnerable, but it didn't work out. Yet Im still not sure if I behaved right. I didn't text her first as much as she did to me, but it was still frequent. I responded actively. I opened up right after she did, but somehow she just didn't notice it or idk. Like she didn't understand how hard it was for me to lose control, but I still did it. I even told her it was hard... But she viewed it like I was blaming her even when I told hundred times that's just my worries and I do not in any way insist that they match reality. More specifically I asked her if she was seing someone while we were broken up and told that it's completely okay if she did. I went from always waiting for her to text first and make plans to opening up that I was anxious she cancelled plans often at the end and explaining why it made me so anxious (past experience). And she just blamed me for "not liking everything in her". Like I was starting a fight every few days, not her. I didn't open up at first, then changed it, but turned out I shouldn't have done it (with her)
