Should I say goodbye to my girlfriend before leaving?

Make an attempt to say goodbye by reaching out to her somehow. If she allows you to reach her, good. If not, also good. You did your part.

”...part of me is telling me to just leave without saying goodbye which I know is a bad thing to do but might ease the heartache for the both of us.”
You might think it might ease your heartache, but how about hers? Imagine if your girlfriend just left the country one day without having told you they were going to go!

“And actually the reason why she doesn’t know I’m leaving was because she’s been ghosting me for 2 weeks now and even blocks in Instagram.”
And do you know why? Could it be because she figured out you are leaving and not telling her?

Are you leaving something out of what you wrote to us, or does part of you leave these things out when relating to her? These are some very large gaps either way. I think you should ask her what is up and tell her you are leaving, both.

Even from an entirely selfish and ego-defensive perspective, leaving without communicating is going to leave two large incomplete issues for you and for her. It’s a common human defense strategy to avoid difficult things like this to try to avoid upset, but there’s stuff that wants attention here, and ignoring it won’t heal it.

Sounds like she’s already said goodbye, whether she knows you’re leaving or not.

For my own peace of mind I would say goodbye. As @Darth_Algar points out, maybe she already knows or perhaps she is just over you and trying to move on without confrontation. Either way, the die is cast. Making the effort is the morally right thing to do, you know it, you just don’t want to do it but in the long run you will have a better opinion of your actions and of yourself.
And, who knows, maybe her opinion of you will rise a notch also. Over time.

You should say goodbye for both your sakes.

No matter what she’s been doing, saying goodbye to her is the right thing to do, in my opinion.

It wouldn’t hurt to leave her a very casual note of some sort be it verbal or written. But be emotionless, final.

@kritiper so you think meeting in person is not a good idea?

@wcarsenal I think if you’ve been dating for 8 months, an in person meeting is warranted.

She’s been ghosting him and blocking him on social media. What makes anyone think she even wants to see or hear from him? Sounds like she’s moved on already.

@Darth_Algar sure she might have moved on already, but like I said. This is about me moving on not her. Sure I would like know why she did this but if she doesn’t wanna tell me fine, I just want to say what I want to say to her before I leave and I understand it might not mean anything to her but it will to me knowing I said what I wanted to.

Send her a card. No return address. Short note saying you enjoyed your time with her (if that is true) and that you wish her the best for the future.

Really.

There is no upside to trying to say good-bye in person to someone who doesn’t want you to contact her.

You’re awfully focussed on saying what you want to say to someone who doesn’t want contact from you. That suggests that she could be right to have taken that stance.

@wcarsenal: Did you leave? Did you say goodbye?

@wcarsenal You might scare her into thinking you are a threat to her safety. Best to do it from afar. In writing.

@jca I did. I sent her a text, I explained everything and asked why she stopped talking to me but she never explains I got the feeling there’s another guy. Anyways it doesn’t matter now

@wcarsenal I think you did well. Good luck!
