How to show a Taurus man you love him?

I met my Taurus man 5 years ago. We were together and broke up and even after we broke up we were still in love. For years he tried to get back with me as much as I wanted to. I didn't because I felt he deserved so much better than me. My closest friend told me he kept asking about me and that he still liked me. A few months went by and I guess he moved on.

So that fall I started school and forgot he went there. When I first got to school to find out my classes he poked my shoulder and I turned around and it was him. Just seeing him makes my day...just being next to him makes my day. Then I found out he had a girlfriend. But every time I would pass him in the hallway are eyes would lock together. we couldn't keep are eyes off each other and it's been that way for years. I can be in a room and not see him and know he's there I can feel him. its like were spiritually connected...he'd even be standing right in front of his girlfriend and still stair at me. it's like we half to look at each other and as cheesy as it sound when we'd look at each other and it was like the whole room stopped nobody was there but us. I'd always make fun of those cheesy love movies and shit but maybe they are real. it just rarely happens to a lot of people.. I know he is my soulmate I can feel it...We he had called me one night saying how he wanted d to be together for one night and finish what we let off...and how he loved me and his girlfriend but it was a lie...I know it was.. he loves me and that his whole relationship with that other woman is just a lie...The thing I like about him was that he was a romantic and I had a rep for being kind of a bitch well more like a little troublemaker back in the day. But really inside I was a sweet girl and he saw that in me.

There not even happy together me and my Taurus man would never argue. His girlfriend would ask me questions about are past relationship. She looked intimidated when she talked to me or when her boyfriend would stair at me while she was next to him in the hallway. She asked me questions about when we were together and if we ever had sex. She told me how he said I was the first girl he ever loved. She'd look at me all the time and say hi to me but she would have that look in her eye like she has that question she wanted to ask me but scared of what the answer might be. She was a sweet girl and I was never the type to break up a relationship even if I thought he belonged to me. It's not my style. I know he wants me but doesn't want to get hurt I think he thinks that there no guarantee that always be there. His girl will never leave him even if he treats her like shit.

So my first questions is. What do I do to show him that I still love him and will always be there for him?
