Samsara

Hi All Reading. I just have a question or 2 that I just can't answer myself, so I thought I'd get the opinion of others. I will start off by saying that me and my partner have been together for 6 years. He is a Bus/Couch Driver and works loads of hours-@ every chance it seems. He is the kind of person that can't hold down a job for a long period of time, (longest one lasting 2 years). When he left his pervious job, I noticed there was a couple of numbers for his works... He named them "Work 1 and work 2" in his fone book. I took out the work 2 number and rang the mobile myself, a woman asnwered the fone. I just froze and hung up, to make sure that I was not mistaken, I foned again later that day- same woman answered. Yet again I froze. Anyway on leaving his last employer, the numbers was still there. As a family, we took a trip into town, he led us all into boots, where he went up to a woman (with me and kids there) and told her about him being sacked. Why did he have to make a point of going in to see someone that he only picked up for work (on bus) to notify her of this.?? Anyway after 2 days of getting the number out of his fone,,, guess what?.. He deleted it. Now he is another bus job and yet the same again has happened..There is another "Works2" mobile number in his fone. I did the same again and rang the number..Its a woman.. I just seem to freeze, when all I want to know is why she's in his fone. (( under a works number may I add). I have never been one to be jealous or on a para trip. But this is really driving me crazy now. I am getting all worked up because he gets funny when a bloke so much even looks at me.!!!! HELP !! I can't just ask him out right because he is a good lair and works his way out of everything. (I've seen this with my own eyes) please reply with good advice.!! THANX ALL
