What does this mean?

Okay so I'm getting this feeling that my boyfriend is either busy or isnt into me... :( I feel like crap, I kinda feel clingy as well I just miss him and want to see him again... I'm just waiting for that reply, "Do you want to go hiking with me?" Or "Do you want to go out on a date with me." I kinda see it fading away, I dont know... I sound crazy... :/ I'm trying to have patience. But I get these feelings that he isnt into me anymore Idk.... there could be times he would say his phone dies or his phone crashes, or he forgot to press "send". UGHH idk...
