I think it’s perfectly normal and reasonable for people to split their time between family members and different friends and work and alone time and other obligations. It’s not possible to maintain frequent contact and have frequent get together together with every single friend.

Do you have more of a romantic feeling for him rather than just being friends? Do you feel the same way about your female friends? Being concerned if they don’t hang out with you frequently? Or not calling you daily?

I wonder if this friendship brings you joy? It was miserable when you were in a relationship with him and is miserable when you aren’t. By now you know who he is. He’s been like this since you’ve met. It sounds stressful. Would you consider expanding your friendship circle or taking up hobbies so you aren’t preoccupied with him?

Sleeping all day can be a sign of depression.
