Don't know what I want for myself!!

I am in a love crisis, I was with my partner for 4 years and recently we split for 3 months because of arguing and not getting along and not trusting each other,and I got involved with a guy from my work who I ended up having feelings for, but I called things off because I still loved my ex, now my ex is trying to get me to have another go at things with him and I think I do love him and the thought of leaving him forever and him being with someone else kills me but I also have feelings for my lover from work and he treats me like a princess and we have a huge sexual chemistry that seems to have been lost between me and my ex, if I spend time with each I feel more physically for the guy from work but I love my ex and we were together for a long time, I am so confused and I don't know what I want

Give some thought to these two men, for instance, if the tables were turned and your ex was in your position, you were in his, 3rd party was a darling co-worker of ex. More often than not this scene ends with hurts, hangups, and at best, moments of heavy breathing, and proof of functioning hormones. Think on it:)
