Is it normal that i need somebody to love me purely?

I got involved in a boy who was running a business.I was ready to sacrifice anything for a honest love.After marriage I faced lots of trials.Later he repented.The first 5 years was fine with a daughter and I really enjoyed the love that I had dreamed.our life was shining with the colours of rainbow.Until one day I came to see a shocking sight where I saw my husband near the maid's bed bending over her.I couldnt understand whether he was doing wrong or whether he was there innocently trying to wake her.But it had a bad form on me and i was not in rest until i send the maid away.Again days started becoming sunny for us and we were on the joyful tracks and during this joy I was blessed with a son.Now our family became perfect.I was continuing my studies along with my job.I had to attend in Bangalore and by the time i reached back I came to hear from people that my husband was again involved with the new maid.I heard shocking stories and I left home.I came back for the sake of my children and my parents but till today I never have the sincerity in me to share myself with him.Later I thought of ways to behave normally with him.Last I decided if I do the same mistake then perhaps I might be able to forgive him.SO I got involved with a family friend of mine.But it was not an ivolvement for sex.It was just to share my pains with him as he too had family problems.So we both decided to be good friends and our friendship reached a level where we both couldnt live without each other.SO we planned to go abroad and live together and support our family from there.We started a life but both our partners were not happy with the places they were living.So we decided to start a business for them so that they might be together and they can also get involved in business and they may forget us.But here things turned out against us.I took up the courage and went forward and set up the place for them and later he went and finished the left over work.But problems began to arise between our partners.Both of them could not tolerate each other's behaviour or actions and slowly fights satrted picking up between us.we both took our partner's side.I was accused by both my friend & his wife that I have done evrything wrong in the business.I was shocked to see things changing.The plan we did to be together started making us separate.Today Im in such a condition that neither I have my family to support me nor my friend to see my pain.Im totally alone.I have seen that both my friend and his wife is having a good relation now and I have decided that it is best to allow them to be together.Because love sacrifices.I love him but I see him more happy & perfect with his wife.I have to be happy for them.Today when I cry my heart out I sit & think what have i gained from this relation? Nothing !!!! Except that I have lost my 2 innocent children's love.My quest for pure love landed me in a place where I have no one to hold my hand.
