She broke up with me suddenly when I moved close to her.

Me and my ex GF (M24 and F21) have been talking for a year, and the relationship was getting more and more serious. I am from Lebanon and she from Canada (Montreal).

I finally decided to close the gap and I applied for a master degree and got accepted in her city in Montreal. And I also got a scholarship to pursue that masters with no costs.

I thought this is the universe telling me that she is my girl and the universe is helping me be close with her. When I moved to Canada everything seemed perfect and it was getting better and better with me and her, in real life was even better than long distance.

4 months in she sent me a text that she suddenly
lost feelings, she can’t explain why, and she said it in a cold way like I was talking to a robot. I could see the emptiness in her eyes.

I was devasated, she broke up with me like I’m nothing to her without a single reason after all the sacrifices that I did. And she went and seemed living her best life on social media.

After 6 months she came back and apologized and told me she rushed her decision on breaking up with me like that and she should have communicated more and she feels that her feelings came back.

Is she avoidant? Is that why she switch off whenever we get close and she came back when I took distance from her?

Should I give it another shot? She is my first love and my first serious relationship.

Please I need some opinions.
