Hi spikyn, welcome to the site.
No worries about not being sure where to start. We can "start small" and see what comes up for you, and let that direct where we go.
So how long have you been in your relationship? Any red flags at the start, or have you had some realizations more recently?
Any kids involved (yours, your partner's, shared)? If so, how old are they?
What would you say your top 1-3 challenges/issues/conflicts are in the relationship? Examples might be: yelling, long rants, dangerous behaviors, stonewalling, infidelity, dishonesty, lack of emotional intimacy... (just some ideas to get you thinking).
Reply whenever works for you, and again, welcome to the group
