I’m am 29yrs, a fashion designer and a single mother.
Relationship has always my problem ever after giving birth.
I met this guy from cross Rivers State, last year September, we started dating and everything was going well.
We spend most of our free time together,I went to his house and he introduced me to his family as a friend and introduced a lady to me as his cousin sisters, the relationship continue until last week Saturday that a lady called my number, asking asking me where is my shop located, someone introduced her to me that I sew very well, I directed her, she came and I saw its actually someone I know. After grettings the lady told me she is not here to sew she is here to discuss something important, I say ok no problems.
She started telling me they are not related that she is is supposed wife, hmmmmmm I couldn’t talk I until she was done explaining her self and I told her am not going to say anything until I see the guy to clarify.
So I called the guy, he came when you saw me with her he was shocked, I asked him to explain and he couldn’t say anything, until after an hour plus.
He was saying she has been his friend on social media since 2017, their relationship started officially early this year January when she graduated from college of nursing, when his mum asked to come over to Abuja to search for work, that their whole plans was she will leave after she work for 3 months and get her apartment, but unfortunately Corona started so does not work anymore that’s harsh I have been in the house we are living together,he’s not married to her, if you don’t want to send her packing because of his mom.
