Hey guys looking for advice, my boyfriend and I have been together for nearly 5 years and we are now in an open relationship, the open relationship doesn't bother me it's the fact that I am unsatisfied, I feel left out and plain depressed, I have told him I feel unsatisfied with what we've been doing and nothing has changed (even when I've tried to implement different things) and with the open relationship and feeling left out; we obviously have rules, but he has been seeing the same girl for sex for nearly a year (and she has a boyfriend that doesn't know) and I haven't been with anyone because I've been having to look after our toddler (which I don't mind) but I feel like that is unfair since it has been a year and I've been battling depression for over 6 years and nothing has helped (therapy/anti depressants) I guess I just don't know where to go from here

Sorry for the long post
