My new partner was with his ex for 0ver 20 years & they co parent their teenager . I also co parent my kids . After being on my own for a couple of years I’ve jumped back in the dating pool . Is this normal for someone to always be mentioning so many memories & times shared with their ex to their new partner ? I wouldn’t describe myself as a jealous person ..but question if this is healthy & just means he’s simply deep down so desperately still so in love with her ( she left him over 5 years ago ) .
