Summarize the following:
If you want to cry or scream into a pillow over the breakup, allow yourself to do it. Avoiding negative feelings can extend the time you feel angry or sad. Instead of repressing your emotions, allow yourself to feel the emotions from the breakup so that you can get over it quicker.  Don’t say things like “I don’t care” or “It doesn’t matter,” if you’re still upset about the situation. Lean into the feelings instead. Avoid doing things just to get back at your ex, like dating one of their friends in retaliation. Looking at the relationship from the outside might give you clarity that you don’t have. Think about the reasons you broke up with your ex in the first place. If you weren’t compatible, there’s a likelihood the relationship would have been bad for both of you and was never meant to be.  Even if you didn't want to break up with them, there's still a good chance that you weren't compatible. If you're concerned about your friend because of prior experiences with your ex, it's okay to express that. Just make sure to keep to the facts so that it doesn't look like you're bashing your ex. Signs of an unhealthy relationship include constant fighting, belittling, volatility, manipulation, and jealousy.  You may also may not be financially or emotionally in the same place as your ex. If you have items from the relationship, it may be harder to get over your ex. Get rid of anything sentimental that you own to help distance yourself from them. This will potentially reduce your negative feelings and help you maintain your friendship. Throwing away or tearing up things that remind you of your ex can be a therapeutic experience. Unfollow them or block their content so that you don’t see pictures of them. Following what your ex and friend are doing online is unhealthy and could help feed negative emotions. Distancing yourself from that imagery may help you get over the breakup and prevent you from feeling angry or sad at the situation.  You may also have to stop following your friend if they post photos or information about the relationship that makes you feel angry or sad. You don't have to block your ex, but you can if it makes you feel better.
Allow yourself to feel angry or sad at first. Write down a list of reasons why you and your ex broke up. Get rid of stuff that reminds you of your ex. Stop following your ex on social media.
