Not sure what's going on

Met this Libra guy with a Virgo moon & Venus in Scorpio earlier this year he was having a tough time with his Aries gf & he decided to break up with her. We started hanging out as acquaintances but our chemistry was just too good & I could sense that physical attraction between us. He always kept saying that he doesn't want to be a relationship anytime soon bc he's just too hurt and wants to make it big in his career. After a few hangouts when I was just expecting Friendship from him he kisses me. And I was completely shocked and he said that he likes me but he doesn't know how things are going to work and that he's not ready for a new relationship. Days pass and we get more intimate & he even gave me forehead kisses. Met my family & promised me one day we would make this a committed relationship. His ex would keep calling him and trying to get back with him. But at the same time she was calling his roommates friends and everyone and saying terrible stuff about him that he left her bc she was sick & he borrowed a lot of money from her. I had to leave the country for a few months before I left he promised me that he would be the same when I come back. We would text each other and he would call me a few times each week. But on the phone it would sound like he was just friends with me but he would share personal details with me that he won't share with anyone else. He did tell me that he wasn't much of the cell phone type and could sound distant at times. But during FaceTime he would seem attracted to me & speak dirty.Then about a month later his calls weren't regular & then he told me that he feels numb and brainless and not himself anymore like he's going through a tough phase for him. He told me he's scared to express what he feels towards me as he doesn't want to lead me on & give me hope that one day we will be together.

But he also tells me that i can keep on loving Him. But he just doesn't have hope that one day he can love again and be in a relationship.

The confusing part was he likes me but doesn't want me. Then 2 months following it was terrible no proper response or communication but he did FaceTime me on my bday like he had promised. The next month we started speaking again and he would call me at unexpected times and share personal things and tell me how he's going to help me in my career and goals. Calls for my moms birthday and we FaceTimed each other and it seemed like he liked me but was trying to hold it back. I stopped saying lovey stuff but gave gentle hints about our past. And he told me how though him and his ex are not going to ever get back together he doesn't want to date anyone else & he's super hurt & wants to be single forever. I was seriously crushed that he could say that to me considering the fact that I came after her! And a few weeks after he started saying that I am his close friend. And when I gently stated that his ex has moved on and happy with her new endeavors he says no she won't move on so fast I know about her. I am confused & don't understand what happened between us and neither does she.

And he was actually making some plans with me about what we will do after I come back to town. I thought things were getting better but today I wished him for National Friendship Day & how we both share something special & unique. And he replied saying "I wish you the same. We shall be good friends like this till the end. Sorry." I checked the message and was heartbroken ? And he tried to Call me right after but I didn't answer so he calls my little sister and casually wishes her and asks where I was. I have no clue what to think & he's not the player type. I am going back to my country next month and going to stay in a place 2 mins from him & his ex doesn't live in the same city.

I need help ?
