Repairing a Relationship

I was trying to complete the player asperation, but everytime I tried one gals or guys boyfriends or girlfriends would walk into the lot when I was trying to get the other persons romatic relationship up clear across the lot she stops her feet goes up to the other woman and yells at her. It made the Asperation really difficul tto do, but there is a trick I learned recently that I didn't know at the time, your have to start the relationship until you get some romatic interest once and have friends only, so that it don't put you in the red when you ask to be friends if the levels are right, the relationionship will say friends with benefits. Sims don't seem to be Jealous of though and the romatic bar should turn into a blue or purple bar.
