HELP! I have no one else to turn to but you insightful ladies

So me and my bf got in a not argument but i wanted to know where he stood in our relationship i told him how i felt opened up to him and just said all what i felt, he never responded, he never said anything and he didnt talk to me for days ( which is unusual since we always talk non stop everyday) I hurt i cried and i felt like i had been beaten up and just straight out depressed. He texted me after the 5th day, he told me yada yada and all such other stuff. During those days of pain my friend comforted me he did everything to ease my pain and he listened to me, at the time he had a gf, but before any of this drama my friend had told me he liked me. Today my “boyfriend” says hell change in the way that he doesnt put effort in our relationship i cried and felt relief when i saw him after so many days. But at the same time when my friend texts me and calls me and makes me laugh and tells me cute stuff i feel a tug in my heart. I dont know what to do. I dont know what to feel. I feel overwhelmed.
