Love or career ?

i'm currently turmoiled right now and trying to figure out what's the best thing to do with the dillema i'm facing . i'm really confused of what should be the best decision i should take with this scenario:

I'm going steady in a relationship for 1 year and 5 months now. Despite of the obstacles we've gone through yet we were struggling to continue our relationship.I would say i really had a hard time with this guy for couple of months before we reached 1 year though it's not about thrid party or something it's just that he can hardly get into a long relationship since i'm the only one who lasted that long cuz normaly he only last for 3 months in a relationship so i really valued what we've gone through and because of my patience everything had a good results.We finally met the clan of each other recently and that made our relationship more stronger.Suddently, i unexpectedly recieved a phone call from which it really made me confused, it's a very nice career, good opportunity for my future, however i have to work overseas,i've been waiting for that opportunity quite long time now unfortunately it came to me in wrong time from which i'm into a serious relationship.It made me confused cuz i don't know what to choose,i loved him so much and as much as possible i don't wanna leave him but the opportunity is knocking at my door which tempting me to push through but there's something holding me back., perhaps, i'm afraid to loose him, besides i don't believe in a long distance relationship and i know for sure when the time i come back he won't be there anymore because he's not really living in this country anyway. Though i really don't have any assurance if he's really the one for me either or if he really wanted to settle down.He hasn't mention anything unto that stage yet if what his plan in our relationship.i asked him once if how he see our relationship and if he's sure with us but his answer is"he's not sure yet depends on the situation"though i really felt how much he loves me i just don't know what keeps holding him back. i'm willing to push through the rel. as much as how he want to. Now, i'm kinda running out of time , i only got 1 and a half months to decide which one should i choose between him or my career ?
Hope somebody would have an opinion towards this issue of mine,just wanna hear some comments.. i'm totaly confused.sometimes heart is really deceiving..I don't know what's the best thing to choose..

Thanks

thank you for all of your advices fellas,i just had a hard time to build this relationship and now it's going smoothly and deeper suddently that opportunity get along my way and i'm having a tough time to decide which one should i choose..

"love or career ?"

I would say to choose your career men come and go but you don't know if this opportunity is going to present it self again. I always say if something is going to be it will be. And you said you don't even know if he is looking to settle down with you maybe these are some things you should try to discuss with him get his perspective on it I'm sure he wouldn't want you to give up an opportunity that will be good for you, you also said you don't know if he loves you so i don't see why this is such a hard decision for you, you have so many "I don't Knows" The only thing you really do know is that this job is there for you.

Don't know what to tell you because sometimes when you follow your heart it leads you astray.

Career

career-thats something that will be with you forever, and man-not really
