The Spirit of Love (1993)

Judging by her lavish home, a model is making a fortune doing TV commercials. When her boyfriend/boss comes over and tries to get romantic, the model begins seeing weird and scary visions. Visions of blood flooding her floor, and a three year old boy ghost. It seems that, three years earlier, she was pregnant and caught her husband athletically knocking off a blonde. Husband kicked her down the stairs, which causes her to abort. The ghost is evidently the aborted baby grown up. Back to the present day, hubby has teamed up with a new girl, and is trying to get back into the house and kidnap the boy ghost.
