Hi ChorleyFMcominginyourears, I'm trying a 5 card 'Spirit Spread' to look into your question. Please leave some feedback in exchange for your reading 
Your first card indicates that you're presently either physically separated, or feeling isolated in the marriage. It appears to be a time of solitude and looking inwards, reflecting on events and feelings and trying to gauge exactly where your relationship is at. The key words here are caution and inner knowing, or listening carefully to what you know deep down is the truth of things for you.
Your second card shows things being pulled apart, and movement. This could suggest a physical move to a new location, a journey, or simply an inability to reconcile differences between the two of you. I get the sense that this is where things are headed, or at any rate might look that way. However, there's also potential for you to overcome the factors threatening to divide you and find common ground through talking. Lots of dialogue. If separation seems inevitable, try to keep talking and keep any anger in check if at all possible. Whatever difficulties you're having relating to one another won't be healed in an unfeeling and aggressive atmosphere. On the other hand, if that's his default attitude at the moment, you need to be cautious.
The next card probably describes you in the situation: loyal, warm, well-intentioned, and desperately trying to keep yourself centred and your energy focused. I get the feeling your generosity of spirit is being tested to the max here and your usual flair and capability might've been dampened or 'blown out' by your recent trials. The most important aspect of this card is the encouragement not to let your own light be dimmed by events or the destructive choices others make. You may also feel as though you're 'playing a part' in order to get through the days, while pushing down your real feelings for the sake of appearances. That might be useful to a degree, but it can't go on indefinitely or your lovely light will burn out.
Although it might seem like a distant memory at the moment, in the past there was some sort of success or triumph that deserved celebrating. It might've been simply that things improved between you for a while, or it could be that your current marriage problems are somehow related to work issues. A missed opportunity or a promotion that didn't materialise may have driven a wedge. Alternatively, a success of some kind may have produced a swagger and confidence that somehow devalued your marriage. Difficult to say without knowing more about you both I'm afraid. But regardless, work demands or pressures probably took a toll in some way.
Is he away a lot due to work, or having to move for similar reasons? There's a suggestion that the demands and practicalities of building up a business might've had a devastating impact on your relationship, leaving you alone quite a lot keeping the home fires burning, Perhaps you agreed to that initially but for one reason or another it has proved difficult and the relationship has suffered. There are definitely financial or business difficulties impacting on your marriage and they may even be driving a coach and horses through it.
I don't pretend to be able to predict the future, so I won't give you a yes or no answer here. The situation's subtleties don't allow for that I'm afraid. I'd only reiterate the importance of keeping talking, but being prepared for a split to happen. If it does, try to keep the conversation going to see if that makes a difference. Most importantly, though, be careful not to lose yourself and the priority of your needs, as well as your best qualities, in the shuffle.
Hope that's somehow helpful
