Should I continue my relationship with my girlfriend?

**Are We Beyond Repair?** I (27 female) have been in a relationship with my girlfriend (25 female) for two years, and we've known each other for three. We’ve been looking forward to getting married, but over the last month, many of our old issues have resurfaced. My girlfriend has an anxious attachment style, and she often disregards my requests for a break when things get heated during arguments. Almost every time, she finds a reason to keep talking, saying things like “I just need to say one more thing” or “Let’s resolve this now," even when I’m feeling overwhelmed with anger. It doesn’t seem to matter how I communicate my need for space—whether I’m upset or calm. No matter how long I ask for that break, whether it’s 30 minutes or a few hours, it never seems to be respected. I’ve threatened to leave on several occasions, which only heightens her anxiety. What troubles me most is that I often feel disrespected. When I’m angry, I say things I later regret, which sends me into a cycle of apologizing and making amends, even though she pushes me to talk when I’m upset. It's genuinely frustrating because I know she loves me, but her actions don’t show the respect I need. I even wrote her a detailed letter expressing my concerns before getting married, with the key condition being that she respects my need for breaks when I need them. She becomes defensive when I express feelings of being uncared for, as she struggles to understand my perspective. We have faced other challenges in our relationship (like her tendency to be controlling and inflexible), but the issue with breaks is the most significant for me. Recently, I needed a 30-minute break and locked myself in a room to calm down. This isn’t an isolated incident; she often follows me and ignores my request for space. In a moment of frustration, I suggested we break up, believing she would never change or give me the breaks I require. I regretted that statement immediately, as it caused her to break down in tears. She promised to respect my needs from then on. The following day, she expressed that I should never threaten to end our relationship again. I responded by saying she needed to honor my request for breaks as she had promised. Her response included “be patient with my progress,” which feels like a way of saying she isn’t willing to change. We’re now on our third couples therapist, all of whom have conveyed the same message to her. I don’t understand why she seems resistant to change. Threats haven’t worked, and neither has therapy, leaving me feeling lost. I truly believe she is my soulmate and can’t imagine finding anyone quite like her. However, I can’t shake the feeling of being disrespected and trapped in this relationship.
