Leave or stay

43 year old male here. Been married for 16 years we have had our ups and downs like any relationship but lately things have changed.
She recently started engaging into a very active social life with old and new friends, males and females, something I am not very good at being an extreme introvert myself. I also developed a strong sense of jealousy from her interactions with other male friends whom most I do not know or met.
Our clash comes down to she feeling tied down and needing to launch into the social life without any guilt of making me feel jealous or uncomfortable, and my needs of feeling loved and prioritized.
I am not sure if there is a middle solution to this we have been trying to find one for the past few months but we end up arguing and hurt. Is it time to end this?
