Is he trying to make me jealous? #anxiety

So I (23, M) have been dating my new boyfriend (22, M) for about 4 months now. Thing have been pretty great-communication for the most part is solid, and I love being around him. I have a lot of anxiety sometimes which is my challenge. He struggles with being bipolar.Last Friday we went out to a club to dance for the first time together. We both agreed weeks ago that the concept of a little jealousy (only thoughts) is good as long as it just stays there; we both think that a little bit is one way of showing that someone cares. We both have pretty extensive hookup histories. I've had one relationship before this that lasted 8 months. This is my bf's first relationship.Anyway, I had a pretty good night. My bf was in a transitional phase where he was a little depressive and serious. When he got tipsy, he became the opposite. He was very talkative, etc. We spent the whole night together. At one point when we were taking a break at the bar, my bf told me that some other guy had been checking him out on the dance floor and if he wasn't dating me, he might have accepted the offer. He also mentioned a couple others guys who had flirted with him when I went to the bathroom. He made it clear that he steered them off.I tried to just brush it off but I feel like he was trying to stir up some jealous feeling or response in me. The first thing about the guy on the dance floor just seemed like an odd thing to say...I kind of talked it out with him but I didn't want to have a huge impact on his mood, etc. He has been very supportive of my anxiety since day one and has said that the way he views it, he chose to be with me, so that's a fact. I feel like I should take it as a compliment but it still feels weird. I'm not sure how to bring it up to him. It's been a few days and it's still bugging me. My anxiety has creeped into other realms of our relationship since then. Maybe we should just chat about our boundaries with jealousy? Part of me wonders if he misses the freedom of being single in that regard. I feel like it may have been a more defensive strategy. He was attached to my side for the night (which isn't a bad thing in my book).TL;DR: my boyfriend and I went clubbing. We're both ok with a little jealousy but a few things were said that kinda set off my anxiety. I'm not totally sure how to bring it up with him and to cope. I feel a little needy/clingy/embarrassed about it all.
