Impeach the motherfucker already! If necessary, I would also remind myself that their having lunch with her has nothing to do with the relationship they have with me, which is what I recommend you do. But I was particularly curious about the line in your letter that refers to his having cheated on you and how that has resulted in the birth of the child that now apparently prevents him from being with you. Do any male couples like using chicks like me as a maid or errand girl?
Straight men are equally reluctant to admit the converse. Love and attraction is not discriminatory here. Get them here!
