Questions: Guy's Behavior

I haven’t seen my boyfriend for the past 6 weeks, I’m not worried about him cheating or anything, he is a true workaholic and leaves his workshop late at night. When I ask him to meet up after work he says he is tired and he doesn’t want to just come to my place and make me feel like we’re just sleeping together, he wants to take me on a proper date but he’s just too busy. He doesn’t really open up about his issues and I don’t know what is he going through, he texts me and calls me all the time, but we haven’t seen each other for 6 weeks now. When I ask him he keeps making me feel like I’m too needy and I hate this. I told him that I needed some time apart to think about our relationship, because this is the loneliest I have felt in my life and I hate it. I don’t see why am I the only one compromising in this relationship. Yesterday, I send him a message explaining why I feel so lonely in the relationship and what are my expectations and I told him that I need 2 weeks to think. He’s been messaging me asking me to talk to him, I really love him but I feel so hurt and I need time to figure things out. Should I leave his messages unanswered for the next 2 weeks? Or what? I’m so confused.
