It's understandable that you're analyzing his response closely, especially given the emotions involved. The phrase "You've welcome" could just be a simple typo or an unconventional way of saying "You're welcome." It might not carry any significant hidden meaning.

In situations like this, try not to overthink his response too much. It's best to focus on the bigger picture – which is the fact that he responded and acknowledged your message. If you're interested in exploring where things stand between you two, you could consider having an open and honest conversation with him. Ask him about his feelings and intentions, and share yours too. Clear communication is key in understanding each other's perspectives and potentially moving forward in a healthier way. Remember, relationships are a two-way street, and clarity often comes from talking things out directly.
