So, I want to ask:
1. How much do you love him and how much does he love you? Are you getting married?
Suppose you believe in this relationship. Female, unless you don't marry. A man will not get married unless he is in love. Then, cohabitation is ok. Practice in advance to see how much the other person cares about you, because most people will fail in their daily lives, so avoid the contradictions and conflicts of cohabitation as soon as possible.
2. What kind of mentality do you have, living at your boyfriend's house?
If you love him, that's good. Live together and take good care of him. But what if you just want to eat and drink? You are attached and hope to make use of your life. In that case, I don't approve of your staying at your boyfriend's house.
3. How high is your acceptance?
The acceptance here includes you, including your family, relatives and friends. People are awesome, especially if you are a girl. If there are too many opposing voices around, you are a girl from a traditional family.
You will get gossip from relatives and neighbors and all kinds of rumors about your bad behavior. Living together before marriage is probably more troublesome than not living together, so it depends on your own living environment and whether you have enough courage to accept it.
Please measure yourself. If you can't understand the above, then you naturally know whether it is good to stay at your boyfriend's house without getting married. Therefore, living in a boyfriend's house without getting married is not necessarily a sign of self-love. The main idea is up to you. Your thoughts decide everything.
