My ex, of 4 years, broke up with me in September. I'm 27 and she's 26.
She said because she doesn’t love me romantically anymore, and loves
Me as more of a brother. She wanted me to change my wardrobe, and
Further my career, though I did finish college and I have a great job.

We didn't talk for a month, then after a month we began seeing each
Again almost 6 or 7 days a week, but platonically. I was thinking she
Would give me another chance. 5 week ago, after a 6 month platonic
Relationship, she told me that she went on a date with some guy a few
Times, and she really likes him, and we need to stop seeing each other
For a while. I didn't talk to her for a week, then I called her. When
We spoke I made sure I sounded cheerful, and I told her that I changed
My wardrobe to the way she liked, and I'm trying to further my career.
When I told her that, she told me that she knew she needed to give me
Space to grow. Also, that she's been trying to get me to change for a
While, and that I finally did it "at the end."

3 weeks later I spoke to her in person, and she told me she is seeing
Someone else. When I asked her if she's seeing or dating this guy, she
Could not give me the answer. I told her her that I learned my
Mistakes, and if she is dating I will give her space and contact her
In a few months, and she said "thank you". She told me she misses me,
And how well we got along. And that maybe in a year or 5 years, if
We're both single, that she'll want to try dating me again.

What does it mean? What can I do to win her back?

You better do as she says and do as she is doing, date, explore, and experiment, because that's what she is doing and seems to enjoy it. Hope you do to.

No one can predict the future, but to deal with what's happening NOW, leave her alone and do your own thing. No waiting for her to change her mind, or having false hope that she will.

Sorry, but I doubt you have a ghost of a chance now, or in the near future.

I have gone on dates and been a few women, but it feels wrong. I still love her so much that dating and sleeping with women feels really wrong.

Then don't sleep with them, or have high expectations from dating until you have gotten over her. Date for fun, to make friends.

She's asking for her space so I would let her go. You changed and it still wasn't enough for her. I think she was using them just as excuses to break up. Clothing shouldn't determine a relationship status.

The main issue is that before we started dating we were really good friends for 4 years. Then one night I told her how I felt about her, and so after we dated for 4 years. She her self said she doesn't want to stop talking to me no matter what. But, I think even our friendship is over.

It sounds as though you became a project that was completed. Look at all that you changed because she wanted you to.

If she isn't interested in a relationship now, why would she think that she might be in a year... or five years? If she wanted to be with you, she would be. End of story.

Don't stay waiting in the wings as she checks out all the other options; seeing if there is anyone better. You may have gotten along just fine, but not enough for her to want to take it any further. You are a buddy to her... and that can be great, as long as you aren't hoping for more... which you apparently are.

Wish her well and move on. She obviously has already herself.

She was in your life for 8 years, and you enjoyed it, and now that things have changed, you have to let go annd heal, so someday maybe you can be friends.

Thank you all for your answer.

She told me that she will never find another guy like me, and that she might be making a huge mistake, but she doesn't have those romantic feelings for me anymore. I really feel that we will never be able to be friends again.

You may be right, and I think she was letting you down easy, but see this as a sign it may be time to let other things in your life, make new friends, and do things with others, after a proper period of healing, and regrouping.

You will eventually, we all have been at that crossroad of letting go of the past, and looking forward to the next adventure in life.

You don't, this is why no contact is recommended after a break up. You have, by keeping in touch with her until she found someone else, extended your healing period. NOW, you are feeling broken up, let it sink in, go no contact, stop allowing her to manipulate your feelings with false hope, and start moving on.

I have gone on dates and been a few women, but it feels wrong. I still love her so much that dating and sleeping with women feels really wrong.

Sleep with as many as you can. You will get over her.
