It's challenging to interpret someone's intentions or feelings with absolute certainty based on limited information. However, I can provide some possible explanations for the situation you described:
Nostalgia or Curiosity: Your ex-boyfriend might have asked for a picture out of nostalgia or curiosity. He might simply want to see how you look or what you're up to.
Closure or Acceptance: Sometimes, after a breakup, people may seek closure or a sense of acceptance. By asking for a picture and thanking you, he could be trying to come to terms with the end of the relationship.
Wanting to Reconnect: There's a possibility that he might be interested in rekindling the connection or exploring the idea of getting back together.
Being Polite: He may have requested the photo politely and thanked you for sending it as a way to maintain a friendly and respectful tone in your interactions.
General Interest: He might have a genuine interest in your life and wanted to see a recent picture without any specific ulterior motive.
It's essential to consider the context of your previous interactions, the nature of your breakup, and your own feelings before reading too much into this situation. If you're unsure about his intentions or if it makes you uncomfortable, it's okay to set boundaries or ask for clarification. Open communication can help avoid misunderstandings and provide clarity moving forward.
