In an online debate, a woman said that she was in a very happy place because her live-in boyfriend helps pay the bills and even helps raise her children.
The men responded by saying that such a man is purely transactional. It's not that he doesn't care for her, but that it's not the same as a real commitment because that dude knows he can leave.
Men don't mind using their resources on a woman as long as they are getting supply from her - whatever it is that fits his circumstance. But if she really wants to know if he truly loves her, start bringing up marriage frequently and see his reaction. If he is excited and wants to marry soon, then he really does love her. But if he starts making excuses and feels pressure then he never loved her in that way. She is nothing but a convenient companion for his circumstances.
