Is it normal to question your relationship and moments that happen in it?

Me and my boyfriend are always questioning our relationship and he seems to mentally hurt me quite a bit more than I feel he should. We always forgive each other for whatever we have done and we always say we love each other but there are moments that feel like we are in a hopeless cycle of questioning if we should be together. He is different from me and sometimes I feel his words or things he does is hurtful like for example we went out to eat together he pulled both of my shoelaces and untied them laughing in my face I laughed a bit and told him it was mean and tied them while he laughed at me tying them back. Well on the drive home he knew I had a song stuck in my head and asked me to share with him I was like you promise to not make fun of me? He said “Yes I promise to not make fun of your song this time” I said “This time? What do you mean this time like you will make fun of me again in the future like everytime before?” He seems to think that making fun of how I sing is funny. I’ve been in choir all my life and have won competitions I’m not a bad singer and he’s admitted that but I’ve become so self conscious of it due to his laugher and choice of words I refuse to sing around him anymore and it actually broke my heart. I told him that doing that is not good and he said it was his love language and he was raised that way his normal excuse and I’m not it’s not Necessarily good especially after he bullied his nephew so bad he wanted nothing to do with him and called him weak and more he ignored my words and practically told me same as his nephew. Later we where cuddled up and he shoved me off hard and said get off me. And it hurt me so bad I asked to hug him later and he refused a hug became distant. What does this mean?
