<human>: So I've been with my SO for about a year and it's long distance- like transatlantic long :( We've had our ups and downs but he is generally a considerate and kind guy who is always there for me. Personality wise there are some things that put me off such as differences in ambition and career goals that I thought I could look past but I'm having a lot of trouble doing that. (that's another issue)

My problem is sometimes mostly the distance. I feel guilty about not having enough time to talk to him because I'm very much a face-to-face person and over the internet/skype is killing me emotionally. We don't really have an end date and I have a sinking feeling that he doesn't grasp how difficult the immigration process really is; or maybe I'm just a bit pessimistic. 

The last thing is my career goals. I want so badly to finish school and get into my dream career. I've managed to network a bit and find someone willing to mentor me and help me get to where I want to be and ... not so sure moving to where he is would be a good option in the next 5 years and him moving here wouldn't be a great option. 

I love this guy but I'm just not in it romantically and I feel like I've failed him, failed myself and feel like I'll make the worst mistake of my life by breaking up with him over silly things but I'm feeling so overwhelmed with stress with him and I know without him I'll feel pretty damn bad too.

Can you give me the gist of the text in a nutshell?
<bot>: Long distance relationship taking a toll on my sanity, feeling like a failure if I break it off and afraid of making the biggest mistake by letting him go by getting "cold feet".
