Can I still trust him?

I’m honestly torn. I’ve been getting to know a muslim man on a serious note. We’re talking about getting married. We know each others families. He has always showed me a committed side of him. He only follows me on his Instagram and his family and the same goes the other way around. Today, I found out he’s been lying to me about having TikTok. I don’t mind him having TikTok, I have it myself, but the fact that he lied about it and follows one particularly girl on it has made me question everything. I confronted him and he tells me she’s an old classmate of him. She asked to follow him and he accepted and followed her back. That was his reason. He got angry with me and says I’m being dramatic for no reason and making a big deal out of nothing. He did unfollow her immediately after. Am I really being dramatic? Should I let this go?
