It's important to remember that everyone copes with breakups in their own way, and there can be various reasons behind your ex's actions. Here are some possible explanations for why your ex started following girls on Instagram after your recent breakup:
Distraction and coping mechanism: Following new people on social media, including girls, could be a way for your ex to distract himself from the emotions and pain of the recent breakup. It's common for people to seek out new experiences or connections during challenging times to ease the discomfort.
Trying to move on: Your ex might be attempting to move on from the relationship and explore new opportunities. Following new people on social media might be an attempt to signal that he is single and ready to explore new connections.
Validation and attention: After a breakup, some individuals seek validation and attention from others as a way to boost their self-esteem or confidence, especially if they are feeling vulnerable.
Curiosity and jealousy: It's possible that your ex is curious about your life post-breakup and is trying to gauge your reaction or evoke a sense of jealousy. This is not necessarily a healthy approach to communication but can be a common behavior.
Social habit: Some people have a habit of regularly following new people on social media, and this behavior may not be directly related to the breakup.
Regarding him wanting to remain friends and not wanting you out of his life, it's possible that he genuinely values the connection you had and cherishes the friendship you shared. However, he might also recognize that you need time to heal and process the breakup, which is why he expressed the desire to remain friends but understands the need for space.
It's crucial to give yourself the time and space you need to heal after a breakup. Take care of your emotional well-being and focus on self-growth and self-care. If remaining friends with your ex is something you're interested in down the road, make sure it's a decision that aligns with your emotional state and that both parties can handle the dynamic in a healthy and supportive manner. If you find that staying connected on social media is affecting your healing process negatively, consider taking a break or unfollowing him for the time being.
