confused abt my ex of 4 yrs: the present?

So I met this guy C when I was 21 while I was attending a community college and working on my Associate Degree.He turned 23 the same 23 year we started dating,so nothing of a large age difference.We were a dyfunctional couple for most of the relationship yet towards the end of it we worked things out and learned to better change with things and each other. We dated on and off for 3 years 9 and 1/2 months and finally called it quits in June 2009.Him and I have never spent one of my b-days together though since I am born in July and every year I did something such as trip to Romania for my 22nd b-day but we celebrated early,trip to Salt Lake City and thur out some other states with the family for my 23rd b-day,with my sister in Dallas for my 24th b-day while we were broken up that summer and last summer with my family.This guy has been my pilar in every sense,he knows that I am epileptic and at the university that we both attend when I had a seizure he and I called him he always would get out of class or work to see me in the hospital.He made sure that I was okay,he even transferred to the same university as I did so he would be close to me yet my stupid actions post poned my graduation by 3 semesters.I was supposed to graduate with him yet I am graduating one year later which is sad.Now he is working on his Master Degree and I feel all left behind,we are best friend and chat on the cell but have no idea if he is dating.He is too busy to date especially with Grad School,homework,making all As,his work outs,working 40 hrs a week and anything else he does.I had not seen him in 2months since this semester I terminated my contract for my dorm and my meal plan on campus due to taking 2 online classes and taking one class which is 2 times a week.So I saw him on Tuesday of this past week and we had lunch,I gave him a hug and kiss on the cheek and we ate.I touched his hand to see how he would react and he did not react at all which made me think that he is over me and tonight he confirmed it.He said that he moved on after I told him to tell me that he loves me.He said that chapter is done with and he moved on and he is not waiting for me or something like that or he does not like when people slow him down.I asked him if he is dating and he never answered.Here is the twist though:a while back ago like 2 months or so he asked me to ask my parents since he knew that my family and I were going on this summer family trip to Romania,where I am from, to visit the grandparents if he could come.My mom told me yes then my said yes,they both asked me as what he would come as in the status wise and I told them as a friend.He applied for a passaport then some trouble with my dad's work made the family cancel the trip at the last minute before buying the tickets.I told him and he was disappointed but he asked me if my parents would not mind if him and I by ourselves would go to Romania,Austria and France(yup that was our trip) by ourselves only him and I.I doubt my parents will ever say yes.I am confused why he even asked me that when I told him a couple of days ago not even a week ago and he kept on asking me this a couple of times then tonight he said something else.Any ideas?

Yes he learned a bit of Romanian and was looking forward to meeting my grandparents and where I grew up.I do not understand why only him and I to travel alone...Confusing....
