I've been feeling really depressed since my husband started a relationship with someone else. Background; my husband and I have been together for 6 years married for 5. We started out poly went mono for a few years and opened back up a few months ago. He had someone he was falling for and I had someone I missed that I was dating when we(husband and I) first met so we opened back up and started doing our thing. I ended up getting stood up and ghosted after a month or so of seeing my previous partner (who I have about 10 years of history with mind you) so I blocked him and moved on. The dating scene is a hot mess and I'm having a hard time finding a new partner. That's not why I'm here tho. It just hit me tonight that the reason I'm having a hard time and have been really depressed lately is that I'm feeling like I'm just not enough for my husband. I literally bring nothing unique to the table from his other partner. Me and his other partner are so alike it's crazy. I'm so scared I'm going to lose him and I don't know what to do. At the same time I feel like I can't say any of this to him without making him feel like absolute crap and like he has to leave his other partner which I don't want at all. I actually quite like his partner and we hang out regularly and i don't want to see his partner hurt.
