From personal experience I wouldn't touch a squaddie with someone elses. I think if he is young and joining the army then he shouldn't have a girlfriend to be thinking about, it is going to be intense training and very little chill out time, when he does get time to relax he will be (probably) on the other side of the country and (nine times out of ten) with another girl anyway. i'm not being bitter I come from a squaddie town and that is just the lifestyle, there is b*gger all to do apart from drink your wages at the end of the month and pull a pig.
You seem pretty young also and more concerned that this girl has got it in for you when you went with her boyfriend! I'd have it in for you aswell!
A long distance relationship is a huge strain on even the strongest relationships and you two haven't been together long/ aren't together yet.
I think you shoul give eachother some space and when he gets some leave you two can hook up and take it from there, you're still young and don't need to settle down yet.
Saying that though, there's nothing to stop you giving it a go, but if you do then just go in with both eyes open, and don't antagonise hi ex by making open public displays of affection so soon!
As an ex soldier of some years, I feel a little bit qualified to give you an answer.
If you like him, go out with him, but be careful of your feelings, because he'll get temptations galore from his various postings.
If you feel you like him enough to go steady, then set certain boundaries for him, he may not like that, but if he feels the same about you, as you him, he'll abide by them.
Just because he asked you out is not a good reason to say yes, you didn't mention if you had feelings for him, a history with him...as friends...etc. From what I've seen, typically men that are going into the millitary feel a need to have connections from back home. It can be a lonely and scary time for them...and be watchful that he is not asking you out just for comfort reasons...or to "have a girl who write of calls him regularily" Seek his motives in this situation, and decide how you feel about him! Good luck!
i met my husband 2 weeks before he joined up, we saw each other about 3 times a year for 18 months ( lots of letters and phone calls tho). We went out together for 2 years, were engaged for 2 more and have now been married for 16 years.
if it feels right go for it and dont worry about his ex, she is after all his ex for goodness sake.
if it works good if not then move on and find the one for you.
youre young I presume, so enjoy life
well i decided not to gout out with him because i didnt give him an answer straight away hes decided to go back out with his ex again which tells me hes not that intressted in me so he can get stuffed
