In 10 year relationship was going great now kinda sucky should i give up or hang in there?

If it's only going "kinda sucky" right now then I would say to hang in there and work on it. Find some ways to improve on your relationship. Go on dates again, do things silly together. If it was going really bad and he treated you like crap and was cheating on you etc, etc, etc then I would say not to put up with it and move on with your life. But, it just sounds like you guys need to work a little bit harder to keep the spark in your relationship going! :)
