My boyfriend (21, male) wants to end our relationship because he's struggling to connect with me (22, female).

I apologize for any mistakes in my English since it's not my first language. My boyfriend and I have been together for three months and have known each other for four, having been introduced by a mutual friend who is also my best friend. Most of our communication occurs via text, and we typically see each other once a week. At first, everything seemed wonderful, but I've noticed over the last few weeks that he has been drifting away and acting distant. Last night, he sent me a message expressing doubt about our relationship, saying he feels unable to connect with me and that it seems like we're forcing a connection. I was taken aback because he had never mentioned this before, and I felt a bit lost, so I suggested we talk in person. Today, we met up to discuss things. I asked him what led him to feel this way, and his main points were: 1. He feels our conversations are forced and somewhat artificial. 2. He’s constantly trying to think of things to say but struggles to come up with anything. 3. He believes we are simply not compatible and come from different backgrounds. He mentioned that these feelings started about two to three weeks ago and that initially, he thought the problem might be with him, so he attempted to change certain aspects of himself. However, he ultimately concluded that our differences were at the root of the issue. My concern is that he kept this to himself instead of discussing it when he first noticed, which could have led to brewing negative thoughts that aren't necessarily objectively accurate. For instance, if your love language is primarily words of affirmation and you notice your partner isn't expressing that enough, it doesn't mean they don't love you; it just indicates they express their love differently. Rather than assuming the relationship is doomed, it’s often possible to make small adjustments to meet each other’s needs. If these feelings are bottled up, they can negatively impact the relationship over time, causing one partner to view the other’s actions in a harsher light. For now, we’ve given each other a few days to reflect on our feelings and possibly gain different perspectives from others. During our conversation, it seemed like he believes the only solution to our issues is breaking up. Personally, I don’t view this situation as unique to our relationship; I’ve seen friends face similar challenges in their own relationships, whether early on or later, and they attempted to resolve them because they were invested in each other. I believe we can make improvements if we identify the specific issues, and we should try before resorting to ending things. However, both partners need to be willing to put in the effort, and if he ultimately isn’t interested, I won’t want to force him. What are your thoughts? Is this a common occurrence in relationships, especially at this early stage? Could it simply be the end of the honeymoon phase and him reassessing things without an idealized view? Any advice or outside perspective would be greatly appreciated. I apologize for the lengthy message; I'm just feeling a bit lost at the moment.
