Worries about Maries boyfriend

Today I came home from my second day at my new job and Marie said hi how was your day? And I answered oh just another day at the office. And we both realized that we sounded like an old married couple, heh heh ;D
Actually today at work was very much like yesterday, but today I already felt more sure about what to do. I predict the worst thing for me will be all the walking around and then to remember who has which office. It's a big building with many rooms.
I already smiled to many of the cutest men, heh heh - I just can't help it I love to flirt. A very friendly woman followed me and helped me yesterday and today, and when I was ready to go home today she said that she was sure I would do just fine on monday. I was sooo proud =)
Marie told me she wants to invite her new boyfriend - yeah she even calls him boyfriend now - over to our place, maybe sunday... I told her I would let them have the livingroom to themselves. That's fine with me cause then I can be on the internet here in my private room without anyone asking what I'm doing all the time.
But then Marie was like oooh but he wants to meet you, maybe we can have dinner all three?And I get this unpleasant feeling that he only wants to meet me because he knows I've had girlsex with his new girlfriend - and maybe he even hopes that we just can't keep our fingers from eachothers bodies or something like that...
Oh, and I gotta have a serious talk with Marie about all this *sigh* If she has a boyfriend now how does he feel about her living with me? Last night she and I were kissing before we fell asleep and today she talks about him as "boyfriend"... if I had a boyfriend and I knew he was having sex with someone else - male or female - that would be a problem.
I need to get it straight or else I'm sure it will end in a bad way. It's okay with me that she has a boyfriend... kind of. Okay I'm a little jealoux but I can handle it. We agreed that the sex stuff we do together is only for fun and joy and nothing serious. And right now I'm more than curious about what her boyfriend thinks of it. If it's okay with him etc.
Well, gotta go now, I'll be back tomorrow ;)
