They Never Initiate Love-Making
When was the last time that your partner initiated sex? If they haven’t then there must be a reason for it unless of course, they are on their period. If they are not trying, then try initiating sex yourself and see what happens.
When someone is cheating or wants to break up a relationship one of the first signs is they lose their initiative for sex with their partner. After that, this can lead to a break-up. In some cases, your partner might have sex with another person beside you and they no longer feel as attracted to you as they used to. If it continues like that you will be increasingly unhappy and might even go out by yourself and try to meet new people. It is just the way things deteriorate in a relationship.
