If he is bothered by other men talking to you . . . .
Jesus says,
"if you love those who love you, what reward have you?" (in Matthew 5:46)
So, Jesus wants him to love those men, not treat them like competition or a threat. And if he considers you to be a kind and good person, he should love them as himself by wanting you to be good for them like you are good for him.
Loving and having feelings for you does not make you his possession so he can use you only for what he wants!!
And in case he does have a jealousy problem, he is possibly charming you, even maybe covering up for an anger and abuse problem. And there is a problem an abuser or charmer or other deceiver is going to have if he fools you together with him. He will know he could so easily fool you; and so, if you were so easy for *him* to fool, then someone else could come along and fool you, too, and take you from him! So, he always will not be able to trust you; because, while he can keep you fooled, someone else also could fool you. And so is the trap he has put himself in, so he can not find out how to love while he is willing to deceive and fool and only try to control and use someone.
And so you also are wise to not try to fool a guy, maybe in your desperation to get someone. Or you could get with someone who does not know how to make sure with God. And as you discover the deception about how you really are . . . you can also discover how the "love" is a deception and not so lasting and "strong" like it promised to be.
So-o-o > while we want someone to be easy to fool with our lies and trickery . . . we are not loving that person. Because with God we can make sure about a relationship and about if we should trust someone. So, if I want you to be fooled, this means I do not want you to be able to make sure with God. And there are even ministers who will tell you that you can't make sure with God but you have to "trust" them and do whatever they say.
But God's word says >
"Test all things; hold fast what is good." (1 Thessalonians 5:21)
The only way to reliably test anything is to check it out with God who knows all about you and others and your situation, and His plan.
So, I must not ever try to Lord myself over anyone to use and control anyone. But welcome you to make sure about if you . . . and how you . . . trust me.
After all, we trust God because He has proven Himself; we do not trust Him blindly.
So, take your time. Enjoy discovering someone who loves all people and therefore welcomes you to love and be good for all people and not only him.
