Search Results: getting married after 3 months

My husband has several female friends that he has had for many years. We lived together for almost 2yrs before getting married and I hadn't met nor heard of any of them until 3-4 months after getting married. I had no problem with him having friends of the opposite sex. But he started spending more time with them then me. Not all of them at once. 1 comes they hang out regularly for a month or 2 then they are gone and a new one appears.. Once I allowed 1 of them, who had no where to go stay in our spare room and when I seen a message where he called her babe, said either she had to go or I would. He told her what I said and SHE was gonna leave but he said if she left we were done. Am I wrong to feel that he should not be spending more time alone with the opposite sex then he spends with his wife?
Am I just being jealous or is his actions being disrespectful to me?
