What do you think of the way his guy acted?What does it mean?

I was seeing a barman about 4 months ago. I lost m virginity to him. abouta week afterhe found out hat he wasnt te faher t a baby tht e thaught was his for 1.5 years. He told me that he didnt want anything serious afe his x and was so sorry and felt awful. He then got a gf but I asked his friend if they were serious and he just laughed. His x also told me that he cheated on this new gf (the same as he did to his x before.) About 3 months ago I found out Id misscarried his baby he was so sorry about this. His new gf found out (SHE IS SO POSSESIVE AND HE'S ONLY ALOWED OUT WHEN SHE SAYS ITS OK shes that ind of gf) andwas horrible to me on facebook. Its stopped now because we came to a truce lol. 2 monts ago I was in the club he workd and his gf was there waiting for him to finish work and when he saw me he looked shocked. Basically it's 2 months later now and last night he was working again when I was in the club. I was walking down the stairs and the guy nd I looked at each other as we ped but I looked away after 2 seconds. A bit later then My friend said that whn he saw me he looked at me then away then at my frnd when he served her (wouldnt serve me.) He then went downstairs and when my friend and I went downstairs when he saw me (he would have had to be looking ) he looked away and started sweeping... What does this mean? Was he avoiding me... to scared to make eye contact? or what?
