As a person who has been in this situation before... although it may seem pointless to keep on trying, you must! People can be extremely weak at times in their life, and even if it doesn't seem like you are making an impact, I promise you are! Guys honestly think differently than girls and guys in college are especially weird, but if you care about the guy then you will keep trying. My ex and I have been broken up for over 3 years, and the first of our break-up sounds just like your's, but as I persisted with my friendship and love of Christ... he started to become closer to his family and now we are very good friends.... I am still the one he turns to when times get really rough b/c I have my faith behind me to give him advice and help him along. Like the other people who have posted responses to your question... If it is tearing you up inside to a point where it effects your life then delete him from your life! Do it now before it is too late! I am telling you this sincerely! BUT, if you can't let him go.... then let him know you will be there for him if he ever needs you. Text him or message him every other week or so with an encouraging word or quote from the Bible! It might sound weird... but it worked for me and now that my ex is honestly going through the worst thing a guy could think to go through... he called me to give him encouragement and just to talk about the situation he was going through b/c he trusted me as a sister in God! I have been sending him a quote of encouragement from the Bible everyday and he is the most grateful in the world. Yeah... I will admit that every guy is different, but trying to help them (IF IT DOES NOT HURT YOU IN THE PROCESS!!!!!) is the way to go! Persistence is the key! I wish you the best in your journey b/c it can be a long one depending on the guy! GOD BLESS AND KEEP THE FAITH! I know you can make it through this with God's help!
P.S. Here is something to give you encourgement b/c every good christian needs a helping hand too! I don't know if you have heard this poem, but every time I read it, I am inspired!
ONLY BELIEVE
Has that trial in your life been going on so long
That everything in you screams, "This is so wrong."
You can't understand, it seems God is far away
As with tears you cry out to Him everyday,
If you read God's Word His truth you will see
That He has a job for you and a job for me,
ONLY BELIEVE! is what He has to say
At His feet this problem you must lay,
In His time and in His way
An answer to your problem will be there one day,
Keep on believing, don't lose hope
He'll give you His grace enabling you to cope,
Keep your eyes on Him as to Him you cleave
He has promised He will never forsake you or leave,
Give Him time to work it all out
The devil just wants you to worry and doubt,
Praising Him is one thing He's looking for
To bless you is what He has in store,
So no matter what, even when you don't understand
ONLY BELIEVE! that's what moves His hand.
