Our expert says:
I don't think it has anything a all to do with her relationship with your ex ( ? her father )or with her own ex - homosexuality is quite common, and arises from ordinary families with ordinary relationships, and the sexual orientation seems to be present from birth though only showing itself or coming to be recognized, rather later in life. Its nobody's fauly, and need not be a serious problem.
Maybe there's nothing you need to or should do, depending on whether your daughter was simply informing you ( but is OK about it, herself ) , or asking for advice and help. In the latter case suggest she see a good local counsellor, maybe one associated with a gay/lesbian organization, who will be more able to be helpful without being judgemental.
Sexuality is not a choice or a conversion, but a part of you, like the colour of your eyes. So, love her as a mother should, and be supportive as she makes her own decisions in life, as you would if she were straight.
