How therapy can help “fix” your relationship will vary from one situation to the next. Relationship therapists and couples counselors can offer tools for dealing with all kinds of circumstances. They can help you address issues ranging from parenting frustrations, to emotional or financial problems, to infidelity.
If both partners are committed, every couple can benefit from therapy, whether you are in a serious long term relationship or dating more casually.
Keep in mind that therapy isn’t a quick fix—both people in the relationship will need to put in the work. However, with time and commitment, therapy can help you strengthen your relationship and find happiness with your partner.
