If you are able to convince your spouse that you need to sort out some issues and that you hope to become a better, more understanding partner following your session then they might accept that. Even if you think that the root of the situation is your partner, you should not explicitly say so. During the course of the counseling if both of you are interested to fix whatever problem is brewing in the connection, and then you will be both willing to try out the counselor's advice.
Your own partner might question your suggestion for counseling if you are thinking that there is no more wish for it to be healed. You are able to calmly but firmly tell him/her that going to counseling is a sign that they want to change things for the best and make both parties understand that they have to make adjustments to make their partners happy. These counsellors also provides specialised Emotionally Focused Couples Therapy.
It is never too early or too late to seek connection counseling and you should not be fearful of suggesting it to your spouse. Some couples stay in denial about the real status they got married or partnership and keep saying everything is fine. But the truth is they may be already on the brink of separation. Others are either too proud or shy to go to guidance because other folks will know that they relationship is not going well. The reality is, if we face upwards to the reality now, there might still be time to save the relationship before the variations become truly irreconcilable.
