Don't know what to do anymore

So I'm talking to this guy and recently his ex visited town. They lived together at his mom's house but they broke up and she had to move back in with family since her family moved from this area.

He is 24 and his "ex" is 21... He has a job and a car never had his own place thought I would mention but anyway I'm going to break this story down as quick as possible.

It's been a year now since they broke up but he has been in contact with her this whole time. She came to visit town at the 7 month mark of their "breakup" and she hit him up and asked if she could see him.

Mind you, she blocks his number and changes her number a lot since their breakup and has mentioned to her that it kills him how she keeps doing that to him.

She will do random no contact periods and then contact him then doesn't it's like a month to month cycle.

SO back to what I was saying she came to visit on Valentine's Day and they met up,

and I noticed he wasn't calling or texting me I decided to see what he was up to come to find out

he took her to his mom and dads house so his whole family could see her!!

He still has her nightstand in his room, her clothes, and her lamp all in his room still and

she doesn't even ask about those things she left behind it's like he kept it I want to know why?

I also found out they got drinks and he admitted to her that he was talking to someone (me) out of the blue and he seemed nervous

and shy around her and so they were drinking he said this and the funny thing is he didn't say ANYTHING about me.

NOTHING AT ALL!! All he said was that he didn't like me and never wanted to talk to me and that I hollered at him first which I did.

She then asked we'll do you still love - cut her off right there and said I still love you and I am still in love with you. WTF!!!

Are these signs he is still in love with her?

1. Stalking her from his car without her knowing and when he saw her get in the car with another guy he sped off behind them, following them with loud music

2. Told her he is still in love with her to her face and tells her he doesn't like me and never wanted to talk to me then the next day after the fact he texts her good morning and wats to spend time with her again

3. Smacked her ass (flirting)

4. She asked to kiss him and he said yea so they made out

5. Walked her to her hotel door then after she says goodnight he says To her wait I want to come in

6. Talked to her in a soft voice the whole time they saw each other

7. Shy and nervous around her

8. Let her give him a back massage and he fell asleep

9. Bought and took her to dinner

10. Played a love song while in his car together

11. Eavesdropping when she went outside to make a phone call

12. She text and said I love you so much and he said I love you so much to right away/ she fell asleep obviously so didn't get his message till she woke up he then asked her why didn't you text me back and she said she fell asleep

13. Gave her hugs

14. Complimented her outfits

15. When he first saw her again when he picked her up he asked "You haven't talked to me in 2 months you expect to come back and everything be ok? What if I was in the hospital?" He said this angrily to her

Am I a rebound? Is he really still in love with her? I found all this out from a friend, and texts and seen them about the city... he also saw her mom to and her brother.

Bottom line: She will be moving back to town soon for an apartment. I want to know if he will leave me for her and if I am just a rebound and he is using me for sex. Why did he say he didn't like me ? :-(
