Hi
If you are not thinking about them and they are not on your conscious mind then I suggest they are or should not be a problem to you. I think you are better off without them too :D but thats my personal idea about it
Ok twins is a symbol of duality(dark twin, nice twin...etc), opposites, often duality in thought or consciousness. I had a dream about twins onces and I looked it up and it said ... double trouble followed by double joy. I can tell you I got the double trouble and I got the double joy. Without going to deep into it, the double drouble was material plus more in thought , the double joy was an understanding thought, not that that is interesting for you prob.

But It seems to me you already dealt with your double trouble, at least I hope that was it and now you are going to experience some double Joy. 3 pairs of twins ... 2 pairs for you didn't work out, maybe third time you will meet a nice person who will put you first and maybe you get a nice baby.
Twins and opposites run through the entire dream. First guy leaves you , want you back( duality in him? ) second guy leaves you , wants you back ( again inner struggle),3rd ....maybe just telling you to end the duality in yourself and get some friends in stead of lovers ; Lol Don't look for your opposite twin, look for good friend. My personal vision on relationships is related. In our culture we state opposites attract, find missing person to complete yourself. I always say complete yourself and find someone else who is completed. Then you will both stay happy :D But meanwhile while you develop yourself you keep looking for these persons that make you more whole...
could be something totaly else though, but this explenation looks fun to me;) I hope all this nonsense can help you a bit
