Please give me advice

My partner and I have separated after a 2 year relationship. I know 2 years isn’t long to some, but he was my first everything. He’s my best friend, the one person I can be myself with and know that he accepts and loves me.

We separated because he needs time to figure himself out, and who he is and what he wants out of the world. I totally understand this, we all need time to figure ourselves out. I can’t help but be devastated though. I can’t imagine not having him in my life. We still care so deeply for one another that all of this just breaks my heart. Why am I not enough for him?

I want to show him how much I love and support him by giving him space, but I’m so scared that he will lose all his feelings for me. I know I sound incredibly melodramatic, but I’m really struggling right now. I’m hurting. All. The. Time.

What should I do? How do I make myself feel better? How do I keep him interested in me and show him how much he means to me? Please, any advice, good or bad, will help me right now.
