Is my crush interested in me?

1) Stares at me or looks at me and when I catch him looking at me he turns away.
2) He talks to me only if we are alone. If people are around he will be like I don t exist.
3) We don t talk or know each other. But waves his hand and greets with "hi" if I am alone when he enters church.
4) Once his friend offered to drop me home in his car and before leaving, his friend teased him saying "don t make this an issue in the future" and for that my crush smiled n blushed.
5) I once overheard him asking another girl to drop me home.
6) When I was down he called and texted to encourage me.
7) Mar 2016, he was standing infront of me and I suddenly turned and saw him staring at me. I smiled and he smiled back widely and continued to stare for few more sec.
8) He is very friendly and helps me immediately when I ask him.
9) He always says that I should not say thanks or sorry to him.
10) For last Christmas, I sang for the program. He took a chair far away from the crowd and sat alone where I can be seen clearly. After my song he left home in few mins.
11) For his birthday I wished him with words "God s Masterpiece" and he kept his whatsapp status as "admiring God s masterpiece" for that whole month.
12) One time he stares at me and next time we gather in church he will ignore me and act like I am not there.
13) Now a days he is totally ignoring me.
14) If I send him forwarded messages or any quotes, he replies with a thumbs up smiley. that s it.
