This question is a little too general, and without context, it is quite difficult to help you.
In any case, I can give you the following suggestions:
- If you are married: What do you mean by “bad luck”? Are you contributing to your relationship? What is the reason for your arguments? Focus on that and try to find common ground.
If, on the other hand, you are single and looking for a serious relationship: there are several workings on the dedicated TOZ page to attract an ideal partner (a generic person, please! Performing spells on a specific person may not be an ideal choice). In addition to that, I would advise you to attend places and social environments where you can meet new people. Staying shut at home will not give you a partner.
-To go deeper, you can take a look at your birth chart and your current transits. They will give you a general picture of why you are having problems in that specific area.
