Relationships are hard work. While you might both love each other, sometimes it takes more consideration and care to have a fulfilling partnership. While it’s normal and healthy for a couple to argue, some fights may be bigger than others. Or niggly arguments that cause long-term resentment. According to Marie Claire, a study from the latest Household, Income and Labour Dynamics in Australia followed 4,000 couples over ten years to analyse which arguments caused the most long-term problems. The results proved these six fights were the most likely to end a relationship…. The Smoking Debate In relationships where one partner smokes and one partner doesn’t, having mismatching habits could see the demise of romance. According to the study, it doesn’t matter is the non-smoker says they don’t mind, or that the smoker intends to quit – the study proves that long-term dissatisfaction and disagreement is inevitable when you can’t sync your smoking habits. The Stressed Out Argument The study found that in situations where a male partner is struggling to cope with stress, depression or anxiety, and they’re taking it out on you, then your relationship is more likely to head for a split. While some researchers argue that this could be because some men find it difficult to voice their concerns, others indicate that a lack of open communication is always a stumbling block in building a solid foundation. Introvert –vs- Extrovert Yes, we’ve heard the rumours that opposites attract, but long-term divided opinion on how you want to spend your time or how you want to connect with your partner could cause some serious arguments. If one person prefers adventure-seeking and going out for crazy nights on the town, they may feel resentment at staying in for dinners and quiet nights in front of the fire. Jealousy can even come into play if one partner is constantly spending time with a group of friends. The study found that long-term, cherishing the same activities for quality downtime is the key to a successful relationship. The Education Argument We all know there are a number of ways to mark our intelligence and that experience and skill doesn’t always translate to degrees or qualifications. According to the study, if one partner has a higher level of education than their counterpart, feelings of resentment or insecurity can take hold. The research found women were particularly sensitive to whether their boyfriends had a higher level of education – which could trigger frequent arguments and long term problems. The Flush Fall While we might all dream of winning the lottery, a sudden cash windfall could lead to disastrous consequences. As well as agreeing on how to spend your new-found fortunes, the study found that for those who are dating or living together, a cash injection could bring a series of fights and upset. Strangely enough, the study found that married couples who came into a sudden lump sum of cash managed to overcome the same issues, and enjoy the spending spree together. The Age-Old Argument While we might think the hardest part of love is finding the perfect partner, apparently only time will tell if you can withstand the test of time. For couples in their 40s and 50s, the next decade marks the hardest time in your relationship. Although the study did have a silver lining. Once you make it into your 60s, it’s all plain sailing. Well, once they quit smoking and learn how to chill out.
