Is he cheating on me?

Hi, I am seeing a guy for just over 6 months now. We have a very intense communication since the very beginning: good morning, good night, all day long... We have done so many things together, to me he is a "boyfriend", but I understand his fear of commitment and we never labelled the relationship. I tried to bring up the topic a few times, but I see he is avoidant. He agrees he is avoidant too... Recently, I started being a little bit more demanding as I really want to know where I stand after 6 months of so much intense communication. I really want to make plans with him for the future, go travel with him etc. He is never giving me clear answers when I share that he is dismissing my feelings. I know he likes me, but this is not enough, so I raised the issues. We had some frictions and misunderstandings that changed the dynamics of our energies over the past 3 weeks. Last week he changed behaviours with me: delayed responses, not reading texts but yet online on another platform texting with someone till late or early in the mornings, he even changed his profile picture twice. Basically, he is doing everything he did with me online, but this time with someone else I guess. I have no facts. I am unsure how to bring the topic, without being seen as a "stalker". Can you please provide your insights and suggest some approaches?
