Is Ex Boyfriend Trying to Make Me Jealous?

[DSTIVA99]

So my ex and I are neighbors who moved in two doors down from each other before we broke up. A month after we moved in, I confronted him about his previous stance that we could not move the relationship forward because his parents (whom I never met) won't approve of me because although we are both Brazilian, I was raised in the US and he was not. His parents feel the relationship won't work because of cultural differences and he told me this about 8 months after he started dating but that he would continue to talk to them. After three more months when I finally confronted him, he said things still stood where they stood with his parents and he can't go against what they said even though they told him its his decision to do whatever he wants. I was so hurt but tired of trying to convince him that the relationship is right no matter what his parents think, so I accepted that and he said well he loved me and didn't want to lose me and that things would get better in time. I tried to just be his friend for about a week but I couldn't do friendship anymore because I was so hurt so I asked to go No Contact and asked him not to contact me. He said he understood. A few days later, he's calling my best friend's boyfriend (whom he just met through me) who is staying at my house to hang out and he even came over my house when I wasn't home to invited the guy over to his house for lunch. He told my best friend's boyfriend that things between us "just didn't work out, because he couldn't take my personality" and told the guy about the new girl he's already dating and how he is not serious about her and doesn't want a serious relationship right now but just wants to have fun. Is he trying to make me jealous? Why would he go out of his way to hang out with a guy he barely knows (I just introduced them two weeks ago) and now he's calling the guy now like every other day to come over and hang out. Its weird. Why is he doing this after I specifically said if we are not going to be together, I don't want to be your friend, I just want to get over you and move on?
