【视频文本】Don’t be blindsided! Know the most common signs that your lover is about to leave you.You Will NeedObservational skills Test question Step 1: Look for contempt(对方总是一副不耐烦的神情)Be on your guard if your lover suddenly seems annoyed by everything you say and do — especially if there’s nothing unusual going on in their life that would explain their irritability.Step 2: Ask them to make plans(当你提到规划你们的未来时,他总是敷衍了事)Try to make long-term plans with them. If they won’t commit to anything beyond the next few weeks, and their reasons for refusing to do so are vague, watch out.Step 3: Be wary of makeovers(对方开始非常关注自己的外在)Be wary if they take a renewed interest in their appearance. They may be primping for someone else — or simply sprucing themselves up in anticipation of putting themselves back on the market.Step 4: Size up the sex(在一起的时间变少)Size up the sex.

They’re no longer keeping you in the loop. Being unable to reach them for long periods of time, or their sudden “busyness” when you try to call or make plans, are other red flags.Step 6: The fighting stops(对方不在乎你的看法)Be suspicious if they’re no longer carping at you for things you do that used to drive them crazy. It could mean they just don’t care anymore, because you soon will no longer be their problem.In one survey, 87 percent of respondents said they would rather know the truth about the cause of their being dumped than be lied to.
