In 2011 me and my boyfriend signed a common law paper at the courts in TX we separated in 2019 and I moved to CT are we married or legally separated? Or single?

ask a lawyer because. this is a legal question.

From a tax standpoint, you are single if you are legally separated (not just physically separated), and while Connecticut does not recognize a common-law marriage that originates from Connecticut, it will recognize a common-law marriage originated from a state/district that does recognize such.  Texas, of course, is such a state.

So from a tax standpoint, you will be considered as single if your separation is considered to be legally recognized in Texas.  As @Mike9241 points out, the answer to that question is a legal one.  And if you have not yet obtain a legally recognized separation, then your tax status is still married for your current filing.
