OK well Me and my girlfriend aren't living together first of all and we are both busy people we have been going out for 14 months now and we spend most of are time together on the weekendsnow we have always had fun on the weekends and talked everyday usually at night. Lately though she has been falling asleep on me about 5 minutes into a conversations now I accept that she is just as tired as any of us but its been going on for almost 3 months and I've found myself questioning if she is just losing interest in my or if she's talking to someone else at night and does that just to get rid of me. Ive never been the most secure person earth and I admit that I may have some trust issues sometimes as we lead totally different lives. It just seems like she has a changing attitude towards are relationship she still tells me that she loves me and still wants to get married and have kids. But I can't help but think that something is changed or is changing and I don't know if its good or bad yet I'm just looking for some help or answers to what's going on.

Based on your message alone, we don't know either. You just want some "what ifs" to spark your insecurities even more?

What if you ignore your insecurities?

What if you drop all the drama and calmly talk to her about it? You talk every night anyway?

What if you just keep moving toward the goal? Make sure you two aren't coasting. There should be visible, describable development in your relationship or your drifting apart. There is no such thing as "staying put" when dating. Either you two are growing or waning... and I bet you know which is true!

What if you lose the phone calls and start dating in person again?

In every relationship that is happy and healthy, there is communications, so after she wakes up ask her. I think its more you, than her.

Wow!!
I am having the same problems as you. Me and my boyfriend used to be the closest of friends and now all of a sudden he just stopped calling, and only text's me once a day and that's it. You have it better than me, at least you guys meet up on the weekends. Me and mine don't spend anytime at all. I know how you feel about the trust thing, but you have to remember that you have to have trust in a relationship in order for it to work. I think that you just need to change your attitude, "WE CAN DO IT TOGETHER" you have to tell yourself that your not going to worry about it anymore, your not going to stress. You have to tell yourself that no matter if she's talking to someone else or just losing interest in you, or doing nothing wrong at all. That you are going to be stress free and if the relationship is meant to be then it will be. And if she is doing something behind your back that she isn't the one for you. And that means that there is someone else better for you out there somewhere...
KEEP YOUR HEAD UP AND BE STRESS FREE!!
