Im so sick of being disrespected

I was outed today as a joke. I had told one of friends in private that I was bisexual in August. He was totally cool with it and very supportive. Sometimes he would even ask my opinion on girls. I don't think he was making fun of coming out. it never bothered me because I knew he wasn't malicious. However today we were hanging out with people I'm not that comfortable with. As a joke he said “well you're bisexual so your fine with anyone”. I looked at him for a moment and nervously I chuckled and said stfu. I was so anxiousbecause I wasn't ready for that to happen. Especially because there were other people with us who I wasn't close too... I really didn't want them to know and now against my wishes they know now. After he said that I quickly left. I texted him and said to please not tell anyone else. He apologized and said it was the spur of the moment. He seemed really apologetic and said he would keep it a secret. But I can't trust him anymore. I realized he didn't respect my decision to keep it a secret in the first place and he invalidated those feelings. Am I overthinking this?? Should I even forgive him idk??
