Can FHA lead to relationship collapse?

Hey everyone,

Apologies if this isn't the right subreddit for my question.

To provide context: I'm 36M and my ex is 33F. We dated for 4 months. My ex has been dealing with FHA her entire adult life, and she's been open with me about her health struggles. I'm still learning about this condition.

Unfortunately, she has also faced childhood trauma and difficult past relationships. Lately, she's been under immense work stress, battling anxiety, and struggling to sleep most nights.

As part of her treatment, she's tried various methods, including gaining weight over the past two years to manage FHA. However, this approach didn't work as expected, and she slowly lost the weight. This contributed to her depression, and she even shared that she had suicidal thoughts last year. She openly admitted has an avoidant attachment style.

Our relationship seemed perfect to me; we even confessed our love for each other after 3 months. However, she recently asked for space for two weeks and then broke up with me. She expressed concerns that our relationship moved too quickly and that we weren't compatible. Her reasons didn't make much sense to me, and she refused to discuss them further, citing overwhelming anxiety and unchangeable feelings.

Since the breakup, she has cut off all communication and blocked me after I sent a single text message to reach out following three weeks of no contact, which she said was invasive and disrespectful.

It feels like her mood and personality have completely shifted. There were no fights or arguments during our time together.

I love her and want to make things work. Normally, I'd respect her decision and move on, but given her circumstances, I'm unsure if she will ever reach out. It's been a month since the breakup, and she's currently on a pre-planned overseas holiday for three weeks.

Could her behavior be related to her condition and influencing mood/emotions?Should I attempt to reach out in future? Any advice would be appreciated.

Thank you
