I met a nice guy on a dating site about a month ago.....I am not sure that I believe in dating several men at a time. I would like exclusivity... Is it too soon to walk away?

He is very clear to me that he is not ready to be exclusive and wangts to date other woman. Initially, I was okay with that as long as we didnt have sex, because he would be sleeping with other woman. He was okay with that… but as time is going on , the chemistry is too overwhelming and we just enjoy our intimate time together. Also, he told me that he is only broken up with his ex-girlfriend about 3 months before we started dathing and it completely devastated him and that is why he is not ready for exclusivity… I am just looking for other’s input… I really like this man and I dont want to blow it because of my impatience and the fact that I have been completely honest with him in telling him that I am willing to hang on, cause I think he is worth it…. I have many emails on this dathing site…. I really feel that going out with others will distract me from him. so for now I have chosen to not date others… Please send me what ever thoughts you think might help me… Thank you?
