Im extremely confused, boys are crazy, little help here?

okay, now my Ex bf dumped me about a month ago, he said he felt bad, but he didn'tt see a future in it, it took me awhile but while i was on the edge of accepting it and moving on he texted me out of nowhere with a picture of a ring that i wear, he found another one. well we got to talking and a few days later i asked him if he ment to keep talking to me because he said not to talk to him the 2 weeks he was out of state, well the pic happend a week into it, but i asked him if we should stop cause he said not too talk, but he said no, i like talking to you, it just kept going he didnt mean to hav it happen, well he got back and we kept talking then the other day my sister and his sister had a play date at his house and i came along just to hang out as friends like he wanted, it being the day after the 4th of july i was a tad upset being the 1st 4th without my grandparents. so i looked sad most of the day, but he kept saying dont look sad, and then after i felt better he would tease me, and turn me on and then say it was fun, after an hour or so he played video game and i watched and daydreamed about everything, he kept checking on me, and finally he turned got my attention and kissed me on the mouth, and smiled and said not to look so sad, then we went to the park and i watch the kids while he and his mom went to do errands and pick up our friend jesse, who i was extremely jealous of but then became friends with and now were good, while its been a few days and he hasnt texted me even once, nothing at all, yesterday i went to see jesse(she was staying at his house with him and his friend justin, she is engaged, not to either of them though) and while comming up the walk to his door he jumped out hte back window and his sister told me he said "tell her im not here" while his friends were just like oh this person whos stalking jesse just showed up a few minutes before he must of gone after him.. well we went out to look cause he was supposed to be watching his sister and i saw him coming up the sidewalk, and he saw me and dodged up into the neighbors gr, i went inside and just sat attemptin gto eat a roll, after a while he crawled back into the house through a hole/door cubby in the basement and so his sister went over there and i followed and he was just like i need time to think, i need to be left alone, and im going to just... i dont know what exatly to think, i havent botherd him i mostly text his friends and chitter with them.. cause there my friends too..
