Hello I believe I can help you with your concern
I am so sorry that you still miss your ex-girlfriend after all this time, I can imagine how much it must hurt you to not be in her life
May I ask, why would you want to contact her now after 2 years?
I still love her and want her in my life. Even if its just as a friend.
And what if you find out that she is married and does not want to be in your life?
I won't bother her again. Might lose my mind.
I understand, so you missed her all this time, have you tried contacting her before?
No I haven't. I've thought about her every day since we broke up.
Why did you not try to contact her before since you missed her so much?
I was angry she broke up with me. About a month after she broke up with me she wanted to see me and said that she missed me. But I told her I didn't want to see her. I've regretted that decision. I also found out she started dating her ex-boyfriend. That made me angry as well. But I still missed her.
I know she moved away with him and is possibly married to him now.
Well it is possible that she is remarried or not, but the only way you will find out is if you contact her. I do not see a reason why you cannot contact her, but I just want you to be prepared that it may not go the way that you hope it will go.
Also here is a technique I use with patients to analyse to negatives and positives of particular solution to a problem (e.g. should you call or not).
This can help you objectively look at the advantages and disadvantages of every solution that you want to make
