Me and my ex broke up just over 3 years ago.

I've moved on with someone new & now have a 9 month old and our own place.

My ex Thomas well he moved on with a new girl but still lives at home.

He without a doubt is the love of my life, I lost my V to him, did many firsts with him and he taught me a lot. We were the closest of friends before actually getting together. 

Anyway, when we broke up it got very messy... resulting in us not speaking at all for the past 3 years.

The problem is, I think about him every day. I dream about him almost every night. And I've woke up this morning from another dream, but this ones upset me unlike the others. 

I feel like I miss him so much.

Don't get me wrong, I love my current partner very much & he's the most amazing father to our child but i can't help feel there's something missing. 

Am I being silly? Or is this normal? 

What can I do to get over him? Because I feel like I'm loosing my mind. Another thing that doesn't help is he lives 7 miles down the road from me and works in the same town as me. So I see him in passing quite a lot, we've not spoken a word to each other since we broke up. But when we did break up he said one day he might be able to speak to me again (the reason he couldn't is because he really didn't want to break up) but ultimately we had no choice. 

What can I do guys? I feel like I'm loosing it. We broke up 3 years ago. Why is he still on my mind and why do I find myself dreaming about him all the time? 

Thanks in advance from a very stressed and confused girl.
