''My ex was better in ...''

1) Why They Hate It: I think boys won't like to hear that too. Girls don't like when they're boyfriend talk about the ex and how she was better in cooking or cleaning. 

2) Reason They Hate It: Becouse you are not with your ex, but your new girlfriend. 

3) How Will a Girl React If You Say It: ''They go ask your ex to do (the thing she is better in).'' 

 4) What To Say: ''I love how you do everything amaizng.'' Again you should compliment her,if you offended her with your harsh words.
