Are we growing apart?

[cutygirl]

My boyfriend and I have been dating and living together for 27 months now, he was everything that i was hoped for: honest, nice, loyal, with a good family.... A year ago we met a friend Mike, out of town while they were working in the same company. So my bf saw him as his best buddy then. He invited Mike to move to our home with us while my bf got a new job back home. So Mike quit his job and moved in with us, he rents one of the bedrooms from my bf for 500 a month. Well, long story short, ever since he met this new friend, he was very eager of doing stuff with him, whether it is drinking, outdoor activities, watching tv at home, whatever, there is always Mike! I do feel that my bf and I do not have the lone time like we usually had before. My bf asked him to go anywhere that we need to go, to one point i was so mad. E.g. he would ask Mike if he would like a drink without asking me, i was mad at first, then he gave me a drink with apology, then i felt hurt, then i was in tears... ; e.g. when Mike asked my bf to have a walk, my bf would say yes and go with him eagerly.... but when i aske him, he would just say no......these are just one of those stories that happened shortly Mike moved in with us. Dont get me wrong, Mike is a very very nice person, he does annoy me sometimes but most of the time he is very respectful. My bf found Mike a job with the same company, they even wanted to work in the same shift (3 weeks on, 2 weeks off) . Luckily Mike has to work on different shifts. Okay, now my bf and I are all alone when he gets back from his job, but, he has been very quiet, almost like he is mad..... I know working for 3 weeks in a roll is very very hard, and i know it is mentally and physically exhausting, today is day 3 since he got back, we have not been talking much AT ALL. I dont understand... I was very happy that Mike would not be home so we could enjoy our time together,but now i almost wish that he would be home, so my bf would not be so "dead"...... we did have a fight before he left for work last time, and he was very mad for several days, it was another long story. I think my question is, is he bored with me? I am sure he is not mad at me still but why is he so quiet??? He doesnt even wantto talk! Oh i dont know, i hate this, so awkward.. Please help.........
