My boyfriend and His Ex

I have been with my boyfriend for nearly 3 months. he split with his ex Feb Last yr. they was together for over 2 years and engaged. She was his first love. He broke it of with her. They dont talk, only when they see each other in the street which is about every 3-4 months or so. Last time they spoke was just before Xmas and he got very emotional.

Anyway he bought himself a new car, and he has put a Novelty boxing gloves in there which she gave him they hang of the mirror and a metal tax disc holder, and when he drives home from work he still passes her road (never goes down it never passes the house) and he doesnt have to. He could go another way. Any way the other we pass her as she is parked up outside the shop, she hooted her horn and he stuck his hand out the window and gave a big wave - she waved back. and last night we was driving a bit away from her, no cars in front he seemed to speed up and hoot his horn, she waved and hooted and went down her road.

Any ways she then text him like the new motor ;-) he replied within 5 mins saying, thanks its still a old one htou, hope your well she replied it dont matter what age it is as long as it gets you form a 2 b yeah im alright still cant work but take each day as it comes, hope your well x he then put good stuff, yeah im cool thanks still playin pool and supporting palace ;-) she didnt reply

how do I take all this does he still like her?
