Maybe the Celtic is a bit much for you just yet? I did try it quite a few times when I started, and it usually swamped me. I also changed the allocation of a couple of positions in my standard Celtic spread to ones that made more sense to me.
Slow down and try some two or three card readings until you get to know the cards better. Focus on a day at a time!
I usually read intuitively first, then get a book or look online to find some more layers of meaning. I think its also easier for people to help with suggestions for interpreting one or two cards in relation to a question than a whole big spread.
What I've found is that with a negative card, it can be a warning to keep that thing under control or might suggest that you have negative feelings to deal with.
7 pents - suggests to me that you are stepping back to consider your position. possibly at some sort of crossroads. Interesting that you feel that you are stagnating (the fact that you have interpreted the spread that way reaveals that, I think) - and this card could be seen that way. But now you are aware of the feeling and able to act on it. Standing back mentally and emotionally to look at your situation is a good thing, sometimes.
Ace of Swords - is the card of intelligence and reason. As the obstacle card, it suggests to me that you aren't being logical. Use your reasoning to cut through the emotional fog. Sure, trust your instinct, but consider your options and your motivations carefully. The ace also suggests fortitude and inner strength: you shall overcome.
7 cups - the third card is the foundation of the issue. Perhaps that man in your past is part of some 'castle in the air' fantasy? (Or is your current situation caused by foolish dreams, or perhaps indecision?)
The World - the 4th card is the immediate past. Does this card represent your marriage, with the sense of union, joining together? It seems at odds with your aparrent dissatisfaction. Perhaps someone else will shed some light on this.
The Chariot - the outcome card. Seems very positive to me! If you master your emotions, you can come out on top. You must assert yourself. This card says, "Who are you, REALLY?"
6, the next step: Queen of Pents reversed - to me this is a warning not to neglect your responsibilities. To me she is the earthy mother type, organized, in control of her household but effortlessly so - she isn't a fuss-pot. Warm and dependable. Perhaps you need to focus more on the simple pleasures of life. Enjoy nurturing those around you. Do you need to get more in touch with nature, perhaps? You also need to remember that you are not the only one affected by the situation.
That's my best attempt, but I'm not very experienced, so I hope I haven't said anything inappropriate.
warmest wishes
