Is my guy friend being flirty or not help me pls really confused ?

Ok so weve been friends for almost 2 years now and we used to talk so much like all day on the weekends cus hes not on fb during the week.. and i really really like him but almost a month ago he got a gf and im absolutely heartbroken still im trying to get over it but i cant hes all i think about :( he seems so happy with her i miss our flirty convos but now we barely talk anymore he msgs me in the morning asking if i wanna play ps3 with him but im asleep usually so by the time i see it hes offline :( .... Anyways today we talked for like not even ten minutes compared to how long we used to talk its just now that hes got a gf hes spending so much time with her we never get to talk and it makes me even more heartbroken! But while we talked he asked me a few times when id be able to play cod with him tomorrow and i answered him each time and he kept asking me and he has so many other friends that he could play cod with but we always wants me to play with him (not complaining) i just sometimes think he only wants to play with me cus hes bored or he just really wants to hang with me somehow and everytime hes like go on mic pls he will literally keep saying it till i turn it on. Anyways when he had to get off hes like i gtg ttyl i said k cya then he says byee and hes never said bye to me like that before idk if im over thinking it or do u think hes flirting with me ??? Ugh why do boys have to be so confusing pls help
