Sigh, I believe in the power of my God, but, wow, what a bunch of depressing truths here. There is therein, then, a way to get past going into a relationship with an unhappy person, I think, and, that's to be fully in tune with God in your life and be ready, don't be 'not happy' yourself, as LiamsON excellently put it.
I don't know that I would say so much 'enjoy the ride,' muletrout,

, I like that nic, one of my faves

, anyway, yeah, I would think, anyway, that that's the 'flippancy' way of going into things. I THINK,there needs to be more establishment than just liking to watch whales, as rachedge put it, there must be substance beyond a mere attraction to the same thing.
And, that foundation has got to bigger than life, for Christians, I think, or, the relationship will go sour quicker than you can say, 'Itore's laughing his buns off,' (love ya, buddy

come back soon ) , OK, enough said, except that, we NEED to make a connection, we need buckle ourselves in before we go OUT for a relationship and we need to be seatbelted (love you too buddy, go where He leads, His power is in you) and just ready to go ON FAITH for where He wants us to travel and, I think, I believe, that God will show us a someone who is perfect for us, who can make us become someone who we are NOT and it will be ALL positive because God's plan is in the fold.
Co-dependent, princessaim, yes, there is NO way, unless God has you with that unique social worker personality, that we can be the one that is always having to make the decisions, having to earn all the money in the relationship (now, marriage, that's different, kind of, as roles can be more established, no? ) and is very touchy-feely and possessive. Won't work ! Destined for failure, that kind of relationship
What jordy said is well said, we look at the relationship with the wrong perspective. It takes two to make the relationship work, just like, and, some don't like it when I say this, but, in a divorce, which my parents have done, I remind them that BOTH made mistakes. A relationship, usually, does not end from one person's own self-destroying of the relationship, they have 'help' from their marriage partner
I think, as rickshafe said, that we ARE 'self-absorbed' these days in things like, LOL, the internet and things, and, to meet someone else one has to KNOW that they are going to be committed to someone else IF that relationship is to ever catch fire
And, as julieannie says, don't take a relationship situation lightly, pray, pray, pray, let the Lord show you His way, it's like walking on egg shells, sometimes, you REALLY like this person but just don't know what to do. Ask Him, the Lord will help you through and IF you give it your hardest best shot and it doesn't work out, there should be peace because you went about it His way
OK, I will let us all swim in those thoughts and I thank you all for your answers, God bless ALL your relationships this summer, and, I think, a good place to start with a relationshiip, if you don't have one , is a same sex accountable person whom is on fire for God and can be a helper to your finding a good someone out there. The Lord leads. "...you follow Me."
