She is feeling irritable of late.

My girlfriend of late started getting irritable for no reason... what could be the cause? What do I do? How do I handle this? Does it mean she's seeing someone else? Is she tired of me? Does she want out?

Have you asked her?

Why are you asking a forum? We don't know her so you need to ask her, not us. FYI women get irritable around the time of their monthly cycle.

You posted this in the "Getting Back Together" forum, so I am wondering if she is an ex? Or your current girlfriend?

How long have you been together?

What could be the cause? How should I know? It could be many things. Discuss this with her.

In relationships, one person sometimes picks fights when their love level is going down. Assuming she's sane, you might be able to fix it. You probably took her for granted in the area of respect, trust, romance, or affection.

Ezik, I second the others.. try talking with her. If she doesn't want to talk to you(is irritable overall) consistently(!) it may be a good idea, yes, that it is over.

You wont know what the problem is if you dont ask! You should be asking her, not random people on a forum.
