There could be several reasons why your long-distance boyfriend didn't apologize when you saw him on a video call with another girl he met on Omegle:
He doesn't see it as a big deal: Some people have different perspectives on what constitutes inappropriate behavior in a relationship. He might not see video chatting with a stranger from Omegle as something that requires an apology.
He didn't think it would hurt you: Perhaps he didn't realize that you would be upset or hurt by seeing him talking to another girl on Omegle. Communication and understanding each other's boundaries are essential in a relationship.
He may not think he did anything wrong: If he genuinely believes that video chatting with strangers is harmless and not a violation of trust, he may not see any reason to apologize.
Defensiveness: Some people respond defensively when confronted about their actions. Instead of apologizing, they may try to justify or minimize their behavior.
He feels guilty or embarrassed: Instead of apologizing, he might be feeling guilty or embarrassed about his actions, which could lead him to avoid discussing the topic altogether.
Lack of communication skills: Some individuals struggle to express their emotions or apologize properly. It's possible that he doesn't know how to address the situation effectively.
Regardless of the reasons, the lack of an apology is likely to be a concern for you, and it's essential to have an open and honest conversation with him about your feelings. Let him know how his actions made you feel and discuss your expectations and boundaries in the relationship. Healthy communication is vital for resolving issues and maintaining trust and understanding in a relationship.
