How can I work out this relationship?

My boyfirend is 44 years old and I am 25 . He works in North America and I work in Asia. He had two divorces and had two daughters. He doesn't trust people much specially women.We get to know each other when he works in Asia 3 years ago and I worked for him. We have been together since then.Now his job is not stable and everytime I call him, I had to call his work phone, and he is always busy or not available. I cant control myself calling him so many timesin a day, but this annoys him and I cant find him happy taking my call. I dont like that I cant talk to my boyfriend whenever I want to and I need to know a future with him. I often get stressed and blame him for this. And this recent arguement he said that he cant provide me with what I want and he is not satisfied either. Then after that he doesnt take my call and dont call back even i left message. I dont want a break up, I just want to have a normal relationship. I want to know how i can work this relationship out.

You seem like a terrific girl, but I don't see this relationship working out. It sounds like this guy is definitely gun shy because of his past history with women, so he won't be the most supportive person to have a relationship with. You on the other hand sound like someone that is ready to make a commitment and enjoy a close relationship with someone special. There is somebody out there that will take the time to give you back as much as you are ready to put in, but unfortunately this guy isn't it. Take care, stay strong, and keep looking. I know you will find the right one!

There are about 5 things wrong with this...

Any one of which could KILL a relationship... My suggestion is find a mate a little more suitable.
he doesn't seem to be into you.. dump him.. sorry...
i dont think that he wants a relationship anymore. you have to call him at work. what happened to his home phone? sounds to me that he doesnt want the new woman to know about you. he is always busy or unavailable. never was before.

the man is seeing someone else and living with someone else or he would have a home phone for you to call.

this is not a normal relationship, he is keeping you a secret and has written you off.

time to find another man closer to your age
You have given all the answers. It is break-up time Baby. Get on with life and go look for someone who will love to live with you. May be you will get a much better understanding and compassionate man who is not married and who will be after you. Good luck. Nothing is lost as of now.
My own personal experience.
i think your man is a player, and i don't think he has your time because no mater how busy he is, he still have to find time out of no time to call u, atleast he du go home after the work, can';t he call you after the day work (at night), he must have gotten himself another lover if it is true he did not reply ur voice mail messages, just make up ur mind try and find another man, he may not be the right man for you. and remember out of sight is out of mind.

but incase u still love him and want to be sure of what is making him not to answer or pick ur calls or even reply then i will advise you to pay him an august visit and find out if he as another woman.
