Am I still jealous?

I was cheated on in my first high school relationship, ever since then (20 now) I’ve been the VERY jealous type. It got way out of hand, I would start arguments for everything including women on tv! I always hated being this way. I always tried to change my mind about feeling like this but it never worked. I’m now in a relationship (year and a half) with a wonderful guy. We have been living with each other just him and I for about a year now. At the beginning of our relationship I gave him such a hard time due to my jealousy, would get pissed if he watched movies with sexy scenes. I would get super heated if the movies we would watch had girls showing cleavage. EVERYTHING fired me up and made me feel hurt and upset. I so badly wanted to change. I’ve been trying to change so hard. I’ve been working on it for about 6 months now, I would still get hurt and mad but I kept it in myself and wouldn’t let him know how I felt. Well the other night a conversation came up where he jokingly asked if I was bicurious, I said no but later that night I got to thinking that maybe I am and maybe the reason I get so jealous is because I am. Well ever since that conversation I havnt felt the slightest form of jealousy for anything. We were even watching a show today with a naked scene of females showing everything and he looked at me shocked when I didn’t say anything and just carried on what we were talking about while watching, I didn’t get upset at all and I couldn’t say why. What snapped in me to make me change? Is it maybe because I am bicurious or maybe the saying is real when they tell you “you have to really want to change yourself in order to change” I feel as if I have been really wanting to for a long time but just never let go of the jealousy. I don’t know but I finally feel free. So much has lifted off my shoulders and I don’t feel like I have anxiety about everything!

Also the only reason I think I may be bicurious is because I really thought into it and I do find some females attractive, I would never want to have sex or oral with another female but I do sometimes fantasize about kissing other females while drunk etc. please any ideas of why I just snapped and don’t care anymore?
