I can relate. My ex bf created that “prison” by going fast himself. He asked me to meet his parents one month into our relationship as he saw us serious. I kept pushing back, but met his best friend and siblings. He was clear on wanting to be with me “and only” me. I sensed things were shifting by the 4th month. He was dealing with work stress and family issues. His words and actions weren't matching, and it felt like he was lying to keep me from leaving. He even told me how he gets “too comfortable too soon and take people for granted.” Eventually I asked for a time out so he can make the changes he’s been promising while I calm my anxiety down as I was done listening to him dumping on me his feelings for his ex wife of 4 years (which has lead to issues in his past dating history) . He didn’t like that, he took it as abandonment and he strung me along another month with empty promises, and then broke up with me. I’m still affected by his lack of consideration for my feelings and time, when he convinced me I was his person and he will “never let you down.” I was devastated to see how he changed, or perhaps that was his true self. I showed up, he promised to but didn’t. On a human level, I cannot understand how people are so uncareful with someone’s heart. I think his misleading words and projections were self-serving and more about his personality than his FA style.
