Very good question.. I’m not sure how well I can answer this, although I am in a similar position.. Your S.O. is probably using you if – (and these are crafted from my own experience so i apologize if it is not really what you are speaking about) ... You argue all the time, and they always expect you to work on things, and never end up working on things themselves – ie they are being selfish and expect you to do all the work.. If they seem to lose interest in a lot of things except one or two – for example, my ex-ish girlfriend always still wants to have sex all the time, but when we aren’t doing that, we tend to argue a lot, about stupid things – she tends to start arguments over nothing.. and finds silly reasons to break up, and ends up wanting me back two days later when she realizes she wont be able to have sex with me anymore and I actually won’t be there when she has a bad dream, or to sing her to sleep, or make her laugh, or all those things that make us happy together.. as for dr d above – a lot of what s/he says is true – and going a step further with it, if they are demanding, and you ask for something reasonable, and they completely deny your request.. especially if you have already done a lot for them.. they are probably either ready to move on, not ready for a relationship, just completely selfish, or using you, which is really hard to accept, but I believe is the case, at least in my (non)relationship.. It could be immaturity, or any number of things. I suppose the easiest way is just to be direct about it. Ask them directly, say Seriously, what are you looking for in this relationship, I’m not going to be angry with you, I want to know where I stand, and it may make things easier for both of us if we just level it out. Or something to that effect…. As for breaking up – it depends how much you care about the person. That’s completely your decision. All of my friends and family have told me to move on, but I havn’t yet because I’m convinced that she is the one [and yes, I know this sounds cheezy, and i was one of those people who thought this idea silly, before I met her], and I have never felt this strongly about anything in my life. I’ve had my fair share of LTRs, but there is something different about this one, as cheesey as it sounds, I was not a believer in fate before her, but there is just this immense connection there from the moment we met, and it just feels right, feels like we are supposed to get married and have children together. And with anyone else I would not have taken as much as i have from her. So, really, as to when is the right time to break up, that is completely up to you – no one will be able to advise you in matters of the heart.. the heart is illogical, as it is illogical that I would still give her another chance, but I know I still would, because I love her, but it is the last one I’d be able to take.. As for me, I think the correct time to move on is after you’ve tried everything you can to try to preserve the relationship, if that is what you want, and none of it works. After the breakup, if thats what you decide to do, just keep yourself busy. get your mind off things, dont torture yourself by reading old texts or letters, or looking at facebook pictures, in fact it’s probably better, if you do want to successfully break up, to delete, or have someone hide these things from you if you don’t want them to be completely gone. You will defiantly still miss them and that will be hard – which is why i say I would only do it after every other option is exhausted, so that even if you do end up seeing pictures and things and you get hurt, you will always know that you did try everything that you could. And also – if you really feel someone is very good for you – life is a long twisted road. Even if you do break up, you may meet again and it may be better the next time. I hope at least some of this helped.
