It looks like supermodel Heidi Klum is back on the market. People confirmed that Klum and her bodyguard boyfriend, Martin Kirsten separated a few weeks ago, after dating for a year and half. The ex lovebirds started dating a few months after Klum, 40, filed for divorce from ex husband Seal whom she was married to for several years. A source close to Klum states that Martin, 41, was there for Klum during the difficult time after her divorce. The ex lovers may have gone their separate ways, but Klum is still grateful for the time spent with Martin and all his support. The two will reportedly remain friends, but they will be discontinuing their professional relationship.

Cupid’s Advice:

Learning that not all of your relationships will work out and when to let go are two of the many lessons we must learn in this life. Finding love is hard and the thought of starting over and trying to find someone new can be terrifying, but should you stay in a relationship because of these reasons? What’s the breaking point? Cupid has some advice on how you can tell when it’s time to call it quits:

1. You’re no longer smiling: If you are no longer happy in your relationship it is a major sign you might have to move on. You want to be with someone who makes you smile, laugh and feel alive, and if your partner is no longer making you feel these things you need to ask yourself if the two of you being together is the right thing. Everyone deserves to be with someone who makes them happy, and if you are arguing all the time with your lover or they make you sad  more often than happy it’s time to end the relationship.

2.You both have changed:  As time goes by people can change. Maybe who each of you were and what you wanted when you first started dating may have changed. If you find yourselves drifting a part and heading towards separate paths, it may be time to let go of your love and move on. It’s okay to like different things and do your own thing from time to time, but if you find yourselves constantly fighting about your conflicting ideals or goals, or you are fine with being a part for long amounts of time the relationship may already be over.

3. Is one more into the relationship than the other: For your relationship to work both parties have to be invested in keeping your love alive. Are you both doing your share in the relationship or are you both equally committed to each other? If one of you is pulling more weight than the other, it is a sign your romance may be fizzing out. There could be different circumstances as to why your honey is pulling away, but if you can’t find a way to work it our or fix it together the relationship is doomed no matter what. It’s okay to escape a toxic relationship because sometimes there is too much stress and challenges for you to over come and be able to work it out with your significant other.
