No time for love or relationship butter

So few know this but just a background info - my ex failed 5th time in his degree exam in mid july and he disappeared (he did tell me he wants alone time and that he isnt running away from me ). So it's been 1.5 months. He would check up on me every 10 days and then since last 2 weeks he has been checking up on me every alternate day.However,he did land up a good job in a fantastic company which started 2 weeks ago and I assumed things should now get better but no. When I asked why is he creating so much distance between us and how things have abnormally changed between us,he got mad at me and said nothing has changed. 4 days ago he shared photos of his sister's newborn baby with me and that day went good. He knows i am leaving the country today for studies so last night we spoke on phone for more than an hour after 1.5 months. We laughed and teased each other.Had a great time. He purposely chose phone call over skype,dont know why.Anyway,so while talking to him yesterday on phone,i casually asked if he found a new love interest.He said "i did have a feeling that you'd end up thinking such stupid butter given my behavior lately. There is nothing like a new love interest. I am just not interested in love and/or relationship or any such butter now. It's not that I am too busy,it's just that I am not in that frame of mind now.Not in that mental state now. I have been very natural,my usual self.The way I was before I met you is what I am now. I am enjoying the way things are going now. There is no other girl i talk to apart from you,even now. Your mind keeps overthinking so i am not surprised at this nonsense assumption/suspicion.I promised you I'd never lose in touch with you. Keeping in touch doesnt mean goodmorning goodnight everyday but i again assure i'll stay connected." And then today he msdgd me a great last day at home and asked me to send him my flight details. Earlier he used to stalk my fight until I landed lol,not sure if he'd this time too but whatever.
I dont know what suddenly happened to him with this change in behavior but what I do know is that I still deeply love him and want us to reconcile some time. I am not in a hurry.I am willing to wait. I'd carry on with my life as it is with my academics,friends and family but at the same time I know I want to give us another chance. I know he's not in that frame of mind right now and I dont wanna exactly pressurize him into something but any thoughts/inputs/suggestions in general on this? Thanks
