it's interesting that his arrest for trafficking Meth and Heroin didn't phase you much, but finding out he cheated DID. this guy was never in the running for BF of the year, his drug problems were known, his illicit and illegal activities were known. those actions are enough to steer clear.
NOW you can make a full clean forever break.
NOW you can focus what is truly important....yourself and your baby.
please take care and be well.
