It's challenging to determine the exact reasons without more information about the individual and the specific circumstances. However, there could be several potential reasons why your ex behaves this way:
Fear of commitment: Some people have a fear of commitment, especially when it comes to long-term relationships like marriage. As the wedding date approaches, the reality of a lifelong commitment can trigger feelings of anxiety and doubt, leading them to back away.
Emotional immaturity: Emotional maturity doesn't necessarily correlate with age. Some individuals may struggle with emotional growth and self-awareness, leading to inconsistent and indecisive behavior.
Unresolved issues: Your ex may have unresolved personal issues or emotional baggage from the past that they haven't fully addressed. These unresolved issues could be influencing their behavior and decision-making.
External pressures: External factors, such as societal expectations, family opinions, or financial concerns related to marriage, can weigh heavily on a person's mind and cause them to second-guess their choices.
Manipulative behavior: It's possible that your ex is using emotional manipulation to keep you in their life, even though they may not be genuinely interested in a committed relationship.
Romanticizing the past: Your ex might be reminiscing about the good times in the past and seeking validation or comfort during difficult periods, but this doesn't necessarily mean they are ready for a future together.
Communication issues: Poor communication skills or an inability to express their true feelings and intentions might be leading to confusion and mixed messages.
Regardless of the reasons, it's essential to prioritize your own emotional well-being and set clear boundaries. If your ex's behavior is causing you distress or uncertainty, it might be best to maintain distance and focus on your own happiness. A healthy relationship should be built on trust, commitment, and mutual respect, and it's essential to be with someone who is sure about their feelings and intentions towards you. If you find it challenging to navigate these feelings on your own, consider seeking support from friends, family, or a therapist to gain clarity and guidance.
