Please help me.
My husband whom I go married to for 4years, always fill his form as single, when ever he is filling any form that requires MARITAL STATUS.
and aside from that we don’t normally have any issues (fights) and he doesn’t even have sense of jealousiess towards me,
Is he really inlove with me ?
Why is he always doing that ?
Please advice me what should I do
Am really in pain and having mixed feelings.
