Advice please?

I have a guy friend and we ahve been friends for almost 2 yrs. He just arrived back from Italy on vacation. So last night he calls and leaves me a voicemail and says " I have been texting you for 2 days is your phone broke"? Now he has said this to me several times before i nthe past. I never received any texts from him bec if i did i would ahve recieved them. Why is he playing games? He ahs been acting funny toward me ever since i told him that i was getting married next year. LIke being distant and also playing games. Why is he doing this ? thanks for your help.
