Does he like me? How can I tell or what should I do?

Well there's this guy and I think he likes me but I'm not sure. We texted pretty much all day Friday and he asked what I was doing for lunch so I told him I was going shopping for purses with my 2 friends so he replied back cool sounds fun :D so I was like yeah you can come if you want to so he was like yeah I'll come so we all met up there and the whole time he was just following us not reaally wanting to be in that store purse shopping. So after that we left and he went back to cl and I skipped with a friend so he texted me later asking what I was doing so I was like nothing kinda bored and he was like me to let's do something fun :p so we went for a walk then he texted a little that night and I texted him the next night and today he hasnt sent me a text in 2 days now ididn't either so I'm confused does he like me??� Btw we were Texting til 3am last night about random stuff but we haven't texted at all today and it's like midnight now.. So what should I do??? Advice? (:
