What are your thoughts?

So this is a past situation that occurred. My ex girlfriend and I were separated by covid 19 I had told her I was anxious in this ldr because statistics show these never worked out and became scared to loose her since this was the woman I wanted to marry and have kids with. She seemed panicked that I mentioned I was anxious and our relationship pretty much tanked due to her refusal to let me see her and her inability to communicate. I tried offering to break for her to focus on her health since she was depressed (found out she was faking being depressed for whatever reason) so I tried to make descions that benefitted her health and what was the best for both of us which included tryi g to show love and care to help with the depression during covid so i dropped the focus on sex and even struggled with the ldr sexting shit i just wasn't comfortable. She later cheated on me with her boss and we split and she said she was thinking about coming back I told her no. What is your thoughts? Did I do all I could or were there other things I could have done?
