Love yourself first.....
I agree with the love yourself and devolope a good relationship with yourself first.
Seccondly I will put the poly relationship dynamic down for a minuit and take a different approach here.
When you have a problem of any kind, take a minuet and decied what will make you happy and work towards it. If you are doing something you are not happy with make changes accordingly untill you reach your goals. This works with the things we can change in ourselves only. You can not change others only accept them or reject them. Have reasonable expectations in relationship to work spend to achieve your goals.
What is holding you back from making new connections with others and keeping you home?
