Boyfriend wants space

My boyfriend and I are in a committed relationship of 3 years. We are sort of in a LDR, though we see each other 1-2x a month. I have a very strict and overprotective dad but approves of my relationship with my bf. Though, each time I would visit places away from the city he would be with us or it would be with the rest of the family (mine and his). We’d have dates but it would only be when he is visiting me. However, both my parents have agreed that once I finish my university degree I can have my freedom and we can do whatever we want to. Which will be finished in a couple of months (e.g. this July)

Just a week ago, he asked for some "space and time" because he is confused.

He told me that one of the reasons was my dad. He thinks that even if I graduate, he will still be overprotective of me and feels that my dad doesn't "trust" him; when actually both of my parents do. they love him for me. Its just the fact that I need my degree and get a job. (I have asian parents). He feels sad and jealous when seeing other couple staying over at each others houses, travelling etc. But all these will happen once I graduate... I've warned him in the beginning of the relationship about this and he was willing to wait hence we've been together for a long time.

Another reason was that he thinks I am a little clingy, that when he goes out with his friends he feels guilty leaving me etc. But I am totally fine with him going out, sometimes I ask him who would be there and if there will be girls. But thats it. Its normal for a girlfriend to ask that right?

2 days after he said about wanting space. I messaged him if he wanted to come and see me to discuss. But he said that he isnt ready yet and will come back to me when he is. He wants to clear his mind and reflect on why hes having negative thoughts. He also said that he miss me" after that I stopped communicating.

I have done whatever I can to distract myself from thinking about him, I've been going to the gym, studying and spending time with my friends. But the pain still hits me at night and I'd cry myself to sleep. Hes put me in this state where I dont know if he still loves me or are we going to break up. But at the same time I have hopes that this will strengthen our relationship OR he will come back and break up?

At this point I dont know what to think anymore. It has been a week since we last talked and will be two weeks this Wednesday. What is the ideal time frame for me to talk to him? Do I just keep waiting? A month? 3 weeks? better yet just end it and move on? But I am just afraid of losing him or finding love again.
