I believe that one of the best ways to help a troubled marriage is.. gradually. Try a lot of things all at once & you will catch the other person off guard, they will probably reject your advances (mainly because they weren’t ready for them) & you’ll be no better off.

Start by doing those little things that make a relationship really enjoyable. Touch him when you are talking – not sexually, but just on the hand or arm. Touch is a very special thing and helps bring closeness. Speak nicely to him. Compliment him. Praise him when he does something good or does something well. Let him know by your actions that you think he is sexy or handsome or however you would describe him. Gently rub his butt when you stand next to him. Give him a little shoulder massage when you can get behind the seat he is sitting on. Sit close to him while watching tv, put your hand on his leg – up high, and every so often just brush his member, but do it casually to promote interest.

Treat him the way you would like to be treated. Always think the best of him. Do things together, not separately. Respect him. TELL him you love him – everyday. Look for the good things he does, not the bad. Do all those little things that make people happy. We know people who use http://www.bringbackthespark.com for lots of great ideas for things to do and say, to keep their marriage fresh and alive – they have a section for healthy relationships that want to stay that way, as well as those that are in a rut. It costs so little, yet can make such a difference! Do the things they suggest, and you should stay in sync with your husband, and you will probably find he will do the same nice things for you….happy couple, happy marriage. Remember to be there for each other. Remember too that males and females think differently – it stems from cave man days. His way of thinking isn’t wrong, it’s just different to yours. Your acceptance and appreciation of that will help your marriage no end. Women like to talk about issues, men internalise them.

Plan time for each other on a daily basis to keep the spark of passion from going out, and to get it back if you have lost it. Everyone has the same 24 hours in a day and the couples that last are the ones that take time for each other and don’t make excuses. This maybe after the kids are in bed. If they are late to bed, make some changes to their bedtime – your relationship is too important.

If you get time by yourselves, do you hold his hand? Do you kiss him for no reason, or to just say “I love you”. Do you tell him you love him – do it, daily. When the kids are in bed…lingerie? http://www.pleasurestate.com has great lingerie.

Try a massage night. An all over nude massage (both of you) PRE-PLANNED for say Friday night promotes anticipation and is great fun on the night. Use lots of oil, lie on towels to stop any staining, and go for it – sex is a byproduct of all the fun. Make sure he massages you first – men can lose interest after cu*ming due to loss of a chemical when ejaculating, it just happens. Let him do all the interesting bits.

Try these things gradually (not all at once!!) and you should be fine. Good luck.

Edit:
By the way, after many years of married life, WE still have that "tingling" feeling. I am sure you can both get it again!

In marriage you don’t base you relationship on having that "in love" feeling but on a foundation of "real love". Feelings change from moment to moment. That being said, a person who allows their feelings to control their decision is unstable and immature.

Also, a man who cheats on a woman (who is also his wife, no less) while she’s is carrying HIS child is a selfish and despicable human being.

Also, a marriage can only be fixed if both parties are willing. He, apparently, is not willing. You can’t do it alone.

The best thing you can do is divorce him and make yourself available to receive REAL love from someone who really wants to give it to you. Think more highly of yourself, sweetheart. You deserve the VERY BEST!
