PLease help me?? Marrage in trouble?

I have been with my husband for over 6 year been married for only 4 months and I'm not happy. I like tlaking to other men and would prob do more if had the chance,but I havnt and I love my husband we have 2 kids together, he loves me more then anything in this world. A few weeks ago a friend told him that I was calling another friend of other trying to meet him which I do admit i was calling he forgave me. Now I'm wanting to do the same thing again he doesnt trust me at all, gives me the 3rd degree all the time. It's like I want to be with him but be able to be free at the same time, it's not as easy just to leave we have a house together,Only one car,kids/ I dont want to lose everything and when I start to think about my life with out him in it I dont want to do,He is very upset with everything we arent fighting about everything more talking about it. I dont know what to do anymore I just wnat to run away
