his keeping his options open , what does he want with me

I met a guy abt 3 weeks back. His good looking , good job n very free spirited , loves having fun kinda guy n seemed very interested in me. I like having fun too bt im not so outrageous I could say. Neway we went for cocktails after work. Date went ok I guess except I felt really tired n we had to cut it short.i was also very shy that day. Two days after that we went for ice cream , he sed he enjoyed seeing me n asked wen we meeting again. I sed hopefully soon. Since then his morning msgs stopped , his chats became less. I tried not to think nething of it bt it became a once a day chat in which he didnt even seem interested. But I always waited for him to msg first bcos I didnt wana run after especially if he lost interest. Neway the weekend came n I suggested gng out for a drive or ice cream n he sed he wasnt feeling up to it.the week continued n I never msged until he did for a little but he wud flirt abit with me bt still seemed uninterested in me unlike wen we first started chatting. The weekend came n I dint hear from him. After d weekend I msged to ask hw was his weekend n he sed it was fine n did some stuff at home. Told him I went out n got drunk at my frenz bday. Then he slipped n sed dat he went for supper wid a friend at a very fancy restaurant n dey had 5 bottles of red wine between d 2 of them n got drunk. I just replied n sed wow sounds like u had a fun evening.he quickly changed d topic n asked hows work. I had d feeling he was giving his attention to someone else n I think this friend is d person. I dint chat after n he dint msg me until 2 days later n asked when he is going to see me again. I think his keeping his options open but this ‘friend’gets more of his time dan I do n he sounds like he enjoyed their date a lot. Y is he keeping me around? N wat do I do nw bcos I do like him n wish things worked out for us? Help feeling a little heartbroken.
