Living with him prior to marriage is your personal decision. But know that it has consequences.
In today's liberal world, women moving in with men to whom they are not married has become a common feature.
However, the reality is that women who consent to that arrangement regret it down the road. Some years later, he may get bored with you and walk out of your life like he did his previous girlfriend that moved in with him.
If he pressures you and say you don't love him because you refuse to move in with him, simply understand that he's employing the use of emotional blackmail.
To tell you the truth, moving in with a man to whom you're not married is demeaning - you cheapen yourself. DON'T DO IT.
If you honestly feel that your worlds are miles apart, re-consider the value of the relationship to you. Perhaps he is not the one for you.
As a rule of thub, the man made just for you - 1. Appreciates you - 2. Values your opinion - 3. Respects your right to be different - 4. Seeks to please you and make you happy - 5. Loves you - 6. Is reasonable, is yielding, lets you have your way many times over - 7. tender and affection, considerate, patient, and empathetic.
That is the kind of man you need - the kind of man who will make you happy.
If you current boyfriend does not meet this criteria, he is not the right man for you.
