First of all, it is worth noting that marriage is not an indispensable thing in everyone's life. Some people can live a happy and fulfilling life by choosing to be single. But for those who want to find a partner, if they can't find a partner all the time, there may be the following reasons:

Selection criteria are too high: some people set too high a standard when choosing a partner, which will make it difficult for them to find someone who meets their requirements, thus leading to long-term single.

Lack of communication skills: Some people are uncomfortable in social communication and are not good at communicating with others, which makes it difficult for them to find a suitable partner.

Not serious about feelings: Some people are impetuous about feelings and lack long-term and stable commitment and sense of responsibility, which will also discourage potential partners.

Of course, if a person really wants to find a partner, he can also try the following methods:

Broaden your social circle: You can participate in various social activities, expand your social circle, and increase the chances of contact with potential partners.

Enhance your charm: You can enhance your charm by studying, exercising and wearing, and make yourself more attractive.

Relax the selection criteria: you can appropriately lower your selection criteria and leave yourself more choices.

The most important thing is to respect your emotional needs and keep an optimistic attitude. I believe that time will bring him answers.
