I know your intentions are good and that you want to be a support to him. But sometimes “being there” means backing off. This is a new relationship. Your boyfriend is dealing with very emotional issues. Everyone handles high stress in their own way. His way may be to pull inward and handle important decisions one at a time. He has told you that he needs space right now. That doesn’t necessarily mean the end of the relationship; only that he really does need space.
I suggest you be patient and let him take the lead. If he is interested in pursuing a relationship with you, he’ll contact you when he has the emotional energy for it. You could send him one more (and I mean one more) text telling him that you understand, that you send your support and caring, and that you’ll be happy to hear from him when he’s ready. If it goes weeks and months before you hear from him again, either you two are on different timetables or his life is too complicated to include you.
I wish you well.
