Torn if I should end my relationship about 1 lie?

My boyfriend and I have been together for 7 months. Our relationship is great, a little rocky (hence me writing to this blog) but he is an amazing person. He is suppose to be moving in next month, the talk of marriage and kids constantly comes up. He loves me to bits, he is so romantic, constantly cooks me dinners, he whisks me away on romantic get aways, just truly an amazing boyfriend. Until I was blind sighted one day while he was in the shower, he asked me to text his sister. As I open his phone, I see a conversation with one of his buddys talking about Thailand .. getting ready and preparing for their shots for the trip. I was so confused ... "Why wouldnt he tell me he was going? Maybe he is going to surprise me with a ticket for my birthday (which was the next day)" But nope... not a word ... 2 weeks went by .. and still nothing. So I asked him "What is going on with that trip to Thailand we were talking about?" And the look of guilt came over him. He told me that his buddys planned the whole thing - all he did was give them his passport number. And he wanted to tell me but they wanted this to be a "top secret guys trip." I am hurt ... Why wouldnt he just tell me? And discuss it with me? Expecially because he will be leaving over the Christmas holidays .. our first Christmas together as couple. He works as a truck driver with the guy who master minded the whole thing.... so when he calls me in front of him he puts this machoman act on and says he is going regardless of my feelings ... but when we talk when hes alone he reminds me how I'm the most important thing to him, more important then the guys trip and he wont go. Its not the fact he wants to go on a guys trip - I dont care - but the fact he went behind my back and planned it without discussing it first - leads me to believe he could be lieing about anything? We are still new in our relationship and trying to build trust and he really broke that for me. Can I forgive him?

Hi Thailand1, Emmmm, the secret boys club is a shocker. Yes they (men) can be thoughtless when it comes to 'man' time, but so can us girls be thoughtless. For me this would not be a deal breaker. I would however tell my partner that hiding things, keeping secrets can lead to mistrust, and trust is very important in a relationship. Tell him you dont want to feel like you have to second guess everything he says or does, however if he continues to hide things from you this is what will happen. Let him know, that telling you things that the 'boys' want to be kept secret is not breaking there trust, as you can play along and make out you dont know about any plans, it is building a good solid foundation of trust for your life together. Talk to him, honesty is the best policy in a relationship. If i were in your shoes i wouldnt end the relationship though. Remember a life together can be long and very happy, this problem is just one of many that you will face in that time. think in 10 years time, will this problem still matter? Whatever you decide to do, good luck and go well.
