Watching your ex move on with someone who looks and acts like you can be weird, confusing and upsetting, but seeing your ex dating someone nothing like you can leave you questioning your entire relationship.

Unless you and your ex have the closure talk, you'll never really understand why you two broke up, and why their new partner is so different from you. You can let it eat at you, or you can move past it.

Who they are dating now is a reflection of who they are now, not who you were then with them. Comparison is inevitable, but you should learn to start setting boundaries between your ex and yourself in order to help you heal and move on from the break up.

Their new partner should not be someone you need to worry about, and they should not have any bearing on your self-esteem as much as you may think they should.
