I have never been a jealous or possesive person.
I am very happy with my DP, we have been together for nearly a year. Previous to this I was single for a few yrs, before that in a very off on relationship with an abusive guy and before that I was married to the father of my 3 kids for 12 years.
DP and I are both mid divorce and he has made it clear he wants to spend the rest of his life with me, but not marry again. He makes me feel good, compliments me, makes it clear he thinks I'm sexy, and when he is here we are very touchy feely and have a lot of sex 
. I have never felt this happy with anyone.
He is in the Navy and he lives on the base and spends every weekend with me and sometimes turns up mid week to surprise me when he can.
The yr before we met we both sowed a lot of wild oats and he tells me all about women he met/slept with/dumped 
and he admits he was a complete player before he met me. He was not faithful to his wife. He is not proud of the way he behaved, but in the same token I think he had a lot of fun last year but was bored of it by the time he met me and ready to commit to a relationship.
He goes out about once a month with all the Navy lads and he normally calls me to let me know he is home safely. The last two times he hasn't and he has got wasted, not got in till 3, 4 ,5am and got into trouble at work for being a complete waste of space with a hangover - he has also left his phone at home and last night dropped it down the loo.
Thing is - I am finding it really hard to trust him and to believe his reasons for not phoning (he doesn't have to phone me btw, its just something he does) and I find I am getting jealous and paranoid and finding it really difficult to hold it down, and have almost accused him of cheating on me, which has upset him.
I am behaving like a jealous, possesive idiot and am scared I am going to push him away. I have never had a long distance relationship before and I know I need to trust him for this to work.
AIBU to ask how others deal with this and what I should do?
