I'll try to bring a little clarity to the question with a pertinent answer.
Clarification:: There is no such thing as "poker addict". You're not getting the sweats and shivers if you don't play. So, please leave addiction to actual drugs that deserve the entitlement.
1. Should she even be your wife or he your husband if they are bothered by your passion instead of supporting it?
2. You should not play in secret when he/she goes on a trip, you should be HONEST to each other and SUPPORT each other. Go on a trip together, play poker together and do together what each of you like to do, make compromises for each other. Otherwise go your own way because you are not a couple and what you have is merely a bill-splitting friendship.
3. If someone makes you choose between your passion and your relationship with them, there's something wrong with at least one of you. So, call it even and find someone you care about and who cares about you.
3. If you don't have time for a relationship and for giving a damn about that other person go ahead and chase whatever you care about. Remember that your husband or your wife is a person not your property. So stop being entitled and be true to yourself.
4. If you are actually in a tough situation, then COMMUNICATE, complex language is our advantage over other species, so why wouldn't you use it to it's full extent? Frustrations, secrets, go ahead, if you're married, you're a team, speak it out, find solutions together.
5. There are always ways to mediate issues and you don't need help, you need honesty and care. Go ahead, open up.
6. If you actually have a
gambling issue and you're losing money for "fun". Just stop playing all together. Poker should not be that, and if it is, it's definitely not a passion and you're doing it wrong. Now, go and enjoy your family.
